 https://www.newegg.com/Product/Product.aspx?Item=N82E16811112040
 i got that weblink from my newegg-order-history, lian-li.com pc-65-b can not be searched in newegg anymore. 
  pros : 1. lian-li pc-65b is lightweight because lian-li.com pc-65-b is made from aluminum
         2. comes with harddisk-fan which cool-down harddisk.
            antec.com->300 does not come with harddisk-fan. [source:'antec.com' in https://en.wikipedia.org/wiki/Antec]
            harddisk-fan is more important than case-roof-fan because harddisk gets hot without fan.
            many-air-holes on case-roof without case-roof-fan, is ok.
            many-air-holes on case-roof is important because heat should rise automatically.
            not having rear-case-fan seems ok.
            rear-case-fan maybe evacuate cool-air and hot-air.
            i want cool-air to stay inside computer-case.
         3. thumb-screw for harddisk
  cons : 1. easily scratched
         2. motherboard-tray seems redundant, add more complexity.
            i accidentally pinch power-cable between motherboard-tray and inner-case-wall
            then windows-xp restart by itself randomly.
            memtest86 says memory is fine
            then later i realise power-cable is being pinched between motherboard-tray and inner-case-wall.
         3. fan-size is 80mm, less than 120mm but 2 80mm fans blowing harddisk so airflow to harddisk's hotspots maybe is as good or better.
            but more fan makes more noise but lian-li.com pc-65-b comes with fan installed
            not like antec.com->300 needing additional effort for installing fan.
            some fan specs (cfm means airflow): 
            vantec 120mm 1500rpm 53cfm
                    92mm 1750rpm 28cfm

         4. lian-li.com pc-65-b has air-filter in front-panel.
            air-filter block dust and hinder air-flow. i want maximum air-flow, i can tolerate dust.
            that air-filter can be removed.
         5. expensive
 
 reason i sell this computer in craigslist : [25 sep 2018 7:17 pm edt | 7:33 pm edt add 'i was trying to follow :' | 7:50 pm edt add 'now i realise i must not forget old component which made me survive.' | add 'but bible has flaw' | 11:25 pm edt add 'and maybe that computer is akujiki.' | 11:48 pm edt add 'maybe computer-case with black color makes user feels superstitious.' | 11:51 pm edt add 'but opening side-panel-door shows interior-computer-case color which is not black.' | 12:30 am edt add 'seeing a cat with black color, can make ppl feel superstitious']
  1. i was trying to follow : 
     'Marrying a Woman Taken Prisoner in War
      Moses said to Israel:
      10 From time to time, you men will serve as soldiers and go off to war.
      The Lord your God will help you defeat your enemies, and
      you will take many prisoners. 11-13 One of these prisoners may be
      a beautiful woman, and you may want to marry her. But first you must bring her
      into your home, and have her shave her head, cut her nails, get rid of her
      foreign clothes, and start wearing Israelite clothes. She will mourn a month
      for her father and mother, then you can marry her.' in
     https://www.biblegateway.com/passage/?search=Deuteronomy+21&version=CEV
     then i realise dell's motherboard (american), foxconn, made in china,
     is foreign as well.
     
     now i realise i must not forget old component which kept me alive
     during that difficult-time.
     
  2. i try to follow : 
      'during that year, and when they have all they want from your fields, 
       leave the rest for wild animals.' in http://wortel.ucoz.com/7years.htm

  3. i had bad memory during working with that computer.
     maybe by selling that computer, i won't see that computer so my bad
     memory during working with that computer, disappears.
     but now i realise bad memory can become a lesson for the future.
     and i was trying to avoid seeing that computer for a while, while
     i rejuvenate my mental-strength. then now i can say
     'i realise bad memory can become a lesson for the future'
     
  but now i realise bible has flaw : http://wortel.ucoz.com/bible_flaw.htm 
  and everytime new computer-component is being made, maybe
  iron-miner blows soil with dynamite, killing beneficial earthworm
  to get more iron. 
  https://www.youtube.com/watch?v=7fEJcyMNfII
  (iron mine's good explosion and bad explosion compilation)
  
  and maybe that computer is akujiki.
  akujiki is a blade which wants to be used
  source : 
  'If the blade's hunger is left unsatisfied,
   it will slowly devour its owner's life force. Thus, whosoever
   uses Akujiki shall forever be cursed with an unfortunate fate;
   in order to sustain the blade's hunger, those who wield Akujiki
   must dedicate their entire lives to the slaughter of any and
   all beings that possess Yin, and then they must be devoured in
   their last moments.'

  http://shinobisega.wikia.com/wiki/Akujiki
  from google (akujiki) result 1
  
  maybe computer-case with black color makes user feels superstitious.
  but opening computer-case-side-panel-door shows computer-case-interior color
  which is not black.
  i did not open that computer's side-panel-door during using that computer.
  
  seeing a cat with black color, can make ppl feel superstitious

  review for asus-p8h61-m le :
   cons : 1. in a tower-computer-case :
             there are 2 harddisk sata-connectors on motherboard which
             enforce 2 sata-cable-connectors to face downward,
             making 2 release-buttons on those 2 sata-cable-connector
             face downward.
             so it is impossible to see that downward-facing-release-button
             without ducking.
             so i can forget there is a release-button which
             must be pressed prior unplugging sata-cable-connector.
             
             there are other 2 harddisk sata-connectors on motherboard
             which face upward.
             somehow i used 2 downward-facing-harddisk-connectors.
             i should have used 2 upward-facing-harddisk-connectors.
          2. takes more than 1 mouse click to shutdown 1 cpu core in bios.
             because i always shutdown 1 cpu core in bios to save electricity.
   pros : no other complain.
   suggestion :
    1)maybe if cmos battery is not on motherboard then
      show qestion in console asking
      how many cpu core should be turned on ? ('1'/'a' for all/[number]/'b' for enter 'bios')
      enter today's date and timezone : 12 oct 2018 5:1 pm
      so mouse-click-action is reduced.
    2)put usb-memory inside motherboard to remember user-selection without cmos-battery?
      this idea come during i read https://en.wikipedia.org/wiki/Fujio_Masuoka from 'Fujio Masuoka' in https://en.wikipedia.org/wiki/Flash_memory from https://global.honda/newsroom/news/2018/c180928beng.html from https://global.honda/newsroom/?year=2018&page=3 result 2
      but usb-memory maybe is not worth installing because motherboard-clock still need cmos-battery.
   
 16 january 2017 : 
  bought fan brand insignia from bestbuy, 
  http://www.bestbuy.com/site/insignia-120mm-case-cooling-fan-black/3648006.p?skuId=3648006,
  to be installed in the front of antec.com->300 to
  cool down harddrive
  but power cable of insignia fan, is too short,
  can not reach cha_fan socket on mobo.
  the insignia fan lay on the floor, not used.
  bought 6 inches extension power cable from
  molex power source to 3 x 4 pin fan cables
  in newegg. 
  that 6 inches extension cable provide power to 
  3 fans.
  
 21 january 2017 : 
  while waiting 6 inches extension power cable
  from newegg, i had idea to replace rear fan in antec.com->300
  with insignia fan bought from bestbuy, 
  http://www.bestbuy.com/site/insignia-120mm-case-cooling-fan-black/3648006.p?skuId=3648006
  , made that rear insignia fan move air to interior 
  instead of move air to exterior, 
  providing fresh air to cpu.
  the original antec.com->300 rear fan is now installed in the front
  of antec.com->300, move resh air to interior
  to cool down harddrive installed 
  in harddrive cage level 2.
  
  all side panels, front panel, metal slots expansion
  cover of antec.com->300, was 
  removed to cool down components further, because
  psu location in antec.com->300, suck fresh air from above,
  and above is where cpu is located, so psu maybe
  trying to grab fresh air designated to cool down
  cpu.
  
 9 feb 2017 
  10:52 am :
  last night i was browsing computer case in newegg.com
  then i realised my antec.com->300 can have 120mm fan
  on side panel, moving air to interior for psu.
  
  11:09 am :
  but i realised asus micro atx P8H61M LE
  lacks extra cha_fan socket to provide power to
  120mm fan on side panel.
  asus micro atx P8H61M LE has only 1 cha_fan
  on the left side of cpu, and that is being used
  by insignia rear fan 120mm,
  http://www.bestbuy.com/site/insignia-120mm-case-cooling-fan-black/3648006.p?skuId=3648006

  , to make 120mm fan power cable can plug to molex 
  in psu cable,
  can not fit the 4 pin power cable in insignia fan which
  was bought from bestbuy
  
  i can not find a 120mm fan with power cable eating
  power directly on molex cable from psu.
  
  i doubt 3-pin to molex adapter provided by
  http://store.antec.com/enclosure-fans/truequiet-120-red.html#
  can fit the power cable fan 
  
  11:43 am
  i realised what i bought from newegg.com is 3 pin to molex
  adapter
  https://www.newegg.com/Product/Product.aspx?Item=9SIABU94WV1658&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-
  and 3 pin to molex adapter can not make 4 pin insignia fan
  cable connect to molex.
  the 4 pin cable in insignia fan can not fit 3 pin in
  3 pin to molex adapter from newegg.com.
  but product description says 4-pin, 3-pin, i thought
  3-pin and 4-pin are compatible, apparently not compatible :
  '6 inch IDE Molex 4-pin to Case cooling Fan 3-pin TX3 Multi-Fan Out Power Adapter Converter Cable w/ Speed Reduction ,2x5V/2x12V '

  stripped the screw for fan on top panel of antec.com->300.
  reverse the wind direction for fan on top panel,
  the fan move air to interior, instead of to exterior,
  pushing air to cpu area, psu.
  when tightening the last screw, the drill slips
  then strips the screw. now the screw stuck on the fan.
  next time i must pre-drill the fan with the
  fan laying on the floor, prior mounting
  the fan to computer case.

  i used to live in different room when
  the harddisk does not being cooled with front fan,
  in that room the computer sat near hvac vent blowing
  hot air, 30 celcius was the hd temp at that time.

  bought screw #10 x 1/2 inches hex head slotted made by
  everbilt in homedepot.
  newegg reviewer says slotted head is harder to break
  than phillips head.
  source : 
  https://www.newegg.com/Product/NewProduct.aspx?Item=N82E16811993009&SortField=0&SummaryType=0&PageSize=10&SelectedRating=-1&VideoOnlyMark=False&ignorebbr=1&IsFeedbackTab=true&RandomID=26008701062057220170213143401
  
  apparently the everbilt screw can drill the
  fan and hold the fan to antec.com->300.
  but the everbilt screw protrude from top panel.
  because the hex head of the everbilt screw is bigger
  than original screw from antec.com->300.
  
  slotted head is intended to be used by human.
  phillip head is intended to be used by machine.
  source : 
  1. 'Phillips heads exist because the flat head 
   does very poorly when you have a machine 
   turning the screws. These machines tend to 
   be very powerful and the flat head screws 
   would get over tightened and break. So the 
   Phillips was designed so that the bit would 
   slip out if it reached that point. The down 
   side is that this "feature" works fairly 
   shitty when it's a human doing the work by 
   hand or using a low power consumer drill.' 
   in https://www.reddit.com/r/explainlikeimfive/comments/1m8snq/eli5_why_we_have_two_types_of_screw_headsdrivers/
   from
   google (slotted head harder to strip than phillip head) result 6
  2. 'The Phillips screwdriver was invented in 
   Portland, Oregon in the late 1920s by Henry 
   Phillips in an effort to facilitate the 
   installation of screws using power screw 
   drivers in an industrial setting. His design 
   addressed several drawbacks to slotted 
   screwdrivers, the most common type of 
   screwdriver at that time. One of these 
   drawbacks was the tendency of slotted drivers 
   to over-torque a screw. The Phillips 
   screwdriver was designed to purposely 
   pull-away or "cam-out" when the torque 
   becomes too great. This prevents the screw 
   head from snapping off and also allows the 
   operator to know when the screw is fully 
   seated. Early power screwdrivers did not 
   have torque limiters so cam-out was a 
   decided advantage of the Phillips screwdriver.'.
   'Other advantages of the Phillips screwdriver 
   over the slotted screwdriver:

  stanley 10 pc MultiBit Ratcheting Screwdriver
  http://www.stanleytools.com/en-us/products/automotive-tools/screwdrivers/phillips-pocket-standard/10-pc-multibit-ratcheting-screwdriver/68-010#reviews
  with phillip tip, 
  is the screwdriver which destroyed the head of the phillip screw
  which attach 140mm fan to top panel of antec.com->300.
  the story is :
  my hand was grabbing the handle
  of that stanley screwdriver,  the screwdriver tip has been
  inserted to the screw, when i begin to twist my hand to twist
  the screwdriver clockwise or counterclockwise, the handle
  twist but the shank of the screwdriver does not
  twist immediately, after i twist my hand a lot then
  the shank begin to twist.
  so twisting the handle of that screwdriver, a little, will not
  twist the shank of that screwdriver.
  twisting the handle a lot will twist the shank of that screwdriver.
  so the shank has a delay when responding 
  to the twisting of the handle.
  
  i set that screwdriver to neutral transmission
  when using that.
  but i feel setting that screwdriver to clockwise
  or counterclockwise transmission, does not
  eliminate delay between twisting the handle
  and twisting the shank.
  next time i will use old fashioned screwdriver.

 turned off top fan in antec.com->300,
 cpu load temp = 38 celcius
 cpu idle temp = 31 celcius
 ashburn outdoor temp = 19 celcius
 1 window is opened 3.5 inches
 so top fan is not necessary apparently.
 if top fan is turned on then top fan sucked
 hot, cold air, both hot and cold air rise.
 fan sucks all kind of air, hot, cold air
 source : 
 https://www.youtube.com/watch?v=L41UdAf1VuA&t=7m7s
 
 if top fan is turned off then only hot air
 should rise because physics says hot air rise,
 cool air descend.
 maybe turning on top fan is bad idea because
 cool air should stay inside the case, hot air
 should rise exit the case.
 rear fan still blow air to cpu, and should
 push warm residue air from cpu, away from cpu.
 psu maybe gets occasional warm residue air
 from harddrive fan.

 21:09
 i meant initially top fan was pushing air
 to psu, now i turned off top fan and
 cpu temp remained ok as described above.

 i have done the above long time ago then 
 smelled plastic odor sometimes.
 i smell that same plastic odor again sometimes.
 i smell that plastic odor as i am located 1/2 meter
 away from antec.com->300. but my nose can not smell 
 that plastic odor inside antec.com->300.
 the plastic odor is not intense and not always
 can be smelled.
 maybe that smell came from dust inside psu, i opened,
 cleaned that psu 15 jan 2017 afternoon, 
 but i did not remove psu cicuit board from psu housing
 because removing psu circuit board from psu housing
 need to remove psu cable from small hole in psu cover,
 i fear about detaching psu cable accidentally then
 not knowing how to reattach psu cable.
 reassembling psu cover was difficult.
 paintbrush was used to sweep dust away from 
 psu circuit board then i blew dust away with air from 
 my mouth while closing my eyes, blew dust toward bathtub
 because bathtub becomes clean automatically when
 bathing.

 for long-term stability. (This should not be confused with 
 conventional phase change pads that are pre-attached to many 
 heatsinks. Those pads melt each time they get hot then 
 re-solidify when they cool. The viscosity changes that

 ssd disadvantage : 
 'it can only sustain a finite number of writes before it dies. 
 There is a lot of science that goes into explaining why this 
 happens, but suffice it to say that as the SSD is used, the 
 electrical charges within cells must be periodically reset.
 Unfortunately, the electrical resistance increases slightly 
 with every reset, which increases the voltage necessary 
 to write into a cell. Eventually, the required voltage 
 becomes so high that the particular cell becomes essentially 
 useless. Thus, a finite number of writes'

 ddr4 memory can not be inserted to ddr3 motherboard
 source : 
 google (ddr4 backward compatible with ddr3)
 
 thinking of adding memory to my father's laptop, 
 dell inspiron m5040, currently has 4 gb ram but 3.8 gb ram available
 because m5040 integrated video card must have been eating 
 the rest of the ram (around 2 mb). whether m5040 accepts
 1 piece 8 gb memory dimm.
 'The Inspiron M5040 system supports dual-channel 
  DDR3 SDRAM with memory speeds of 1333 MHz 
  to a maximum of 8GB(2X4GB). You can upgrade depending 
  on the memory currently installed on your computer. 
  If you currently have a 4GB memory module on your system, 
  you can add another 4GB. If your system currently has 2x2GB 
  memory modules, you can either remove one 2GB module and add 
  a 4GB module to make it 6GB or you can add two 4GB modules 
  to make it 8GB. '
 in 
 http://en.community.dell.com/support-forums/laptop/f/3518/t/19660859
 from yahoo (dell m5040 memory) result 1
 
 does that mean 1 memory slot has 4 gb memory dimm size limit ?
 can 1 memory slot accept 8 gb memory dimm ?
 memory power consumption is 4 watt for each memory.
 source :
 'Dell's Power Advisor calculates that
 4 GB ECC DDR1333 RDIMMs use about 4 W each.[12]'
 in 
 https://en.wikipedia.org/wiki/DDR3_SDRAM
 
 so installing 1 big memory dimm is more power-efficient,
 producing less nuclear waste 
 than installing 2 semi-big memory dimm.

 glass side panel can create greenhouse effect, raising temperature

 metal computer case side panel is more protective for transport.
 computer case side panel should be removed when that computer
 is not being transported,
 to allow more air to cool down the interior of computer case.
 aluminium case is easily scratched but lightweight, does not
 induce wood fatigue, metal fatigue on building pillars.

  25 june 2017 maybe between 3 pm to 5 pm,
  i tried to remove heat sink from 
  dell's motherboard for dell dimension 8250
  but failed.
  
  i succeed using a wrench to destroy
  4 plastic screws tips, those 4 tips
  stick out underneath 
  dimension 8250 motherboard tray,
  those 4 screw tips looks like a cone
  which can shrink to 
  penetrate motherboard tray then
  the screw tips cone enlarge 
  so the screw tips can not
  be pulled out from motherboard
  tray, 
  so i destroy those 4 screw tips cones
  by grabbing those 4 screw tips using
  a wrench then twist the wrench repeatedly.
  destroying those 4 screw tips makes
  those 4 screw tips cones 
  thin enough to fit the screw hole and
  can be pulled out from motherboard
  tray.
  
  then i fail using a wrench 
  to push those 4 plastic screws tips
  to unplug those 4 plastic screws
  from the heat sink.
    
  maybe 11 or 12 or 13 october 2017 (dog month), 
  around 7:30 pm est (dog hour), 
  i succeed using a flat head screwdriver
  to wedge away those 4 plastic screws,
  to unplug those 4 plastic screws
  from the heat sink.
  
  then i remove the heat sink from
  dimension 8250 motherboard.
  
  those 4 plastic screws have a screw head
  which is smooth, 
  does not have 'slotted recessed drive',
  does not have 'phillips recessed drive', 
  rather flexible, 
  can be destroyed rather easily. 
  
  if a screw head 
  is destroyed then
  removing that headless screw 
  would be more difficult,
  i stick a flat head screwdriver
  below that screw head then 
  twist that flat head screwdriver
  clockwise, counterclockwise repeatedly 
  to push away that screw head from
  the heat sink.

  custom ordered from lenovo website.
  x60 models, 1 for deborah still works, 
  the other x60 for my father broke after 1.5 years, the warranty
  is 1 year.
  maybe the motherboard broke, that x60 could not boot, 
  only shows black screen.

  july 2017, ram month :
  i broke my dell-dimension-8250's harddisk.
  harddisk model is western-digital wd-caviar wd1200.
  i ran that dell-dimension-8250 without its case.
  i discard that dell-dimension-8250-case after event

  i don't know
  whether republic-garbage-collector
  https://www.republicservices.com/all-in-one-recycling?tab=local

  recycle that case or not.
  
  dell-dimension-8250 motherboard is foxconn-motherboard.
  dell-dimension-8250 has motherboard-tray for
  that foxconn-motherboard.
  i thought that motherboard-tray can become open-air-case
  but no...
  because a stand-alone-video-card has a metal-plate for connector for
  vga-cable, that metal-plate-connector will go below
  that motherboard-tray, trying to puncture floor
  where that motherboard-tray sits.
  i tried putting that motherboard-tray above a 
  cardboard, then i put that harddisk above
  a cardboard as well
  because of harddisk-cable-length-limitation.
  
  so i ran that harddisk sitting above a cardboard
  then that harddisk suffer read-ddmy-dma-error.
  
  then i realised that harddisk-heat comes out from
  underneath harddisk as well as from above harddisk.
  
  so much heat comes out from underneath harddisk 
  even though that harddisk is outside a case....

  i was trying to run that old harddisk from dell-dimension-8250
  to transfer files from my other computer with broken-linuxmint.
  i tried to play crash-bandicoot video-game in my linuxmint then
  i can not boot my linuxmint. then i use that 
  old harddisk from dell-dimension-8250, to save files
  from my linuxmint.

 dell.com did not put hard-disk-fan to cool-down that 2 western-digital->raptor-10,000-rpm-hard-disk.
 so dell.com has good-warranty. but bad-design ? or maybe dell lack supplier willing to supply hard-disk-fan.

or
antec-300 35 usd ( maybe antec-300 because harddisk-position is normal , not vertical but now i realise ssd-price is cheap enough now so maybe i 
choose ssd and choose that new 'Thermaltake Versa H21' then i do not need to buy separate motherboard-screw and power-supply-screw because
pre-owned antec-300 maybe lack motherboard-screw lack psu-screw maybe i will ask seller if i decide to buy )

pcie 2.0 is 100 % backward compatible . pcie 1.x card ought to work in pcie 2.0 motherboard . 
The link will have to clock down to slower pcie 1.x speed . But since that is as fast as that card is designed to communicate anyway , 
no performance will be lost.
