So, I was thinking of building a custom gaming case because I don't really want to spend 100$ on a case with good airflowRight now the case I have the cpu idles at 50C and the video card idles around 60c and 120c+ when gamingI need a new caseI was thinking of putting screw holes in a sheet of aluminum and just mounting the motherboard there and leaving it on the carpet Or maybe making space for it on the desk.Is it safe to use aluminum? Is it the best at absorbing heat to keep the computer cool?Is it worth the trouble to build a 2 floor stand and to put the hard drive, power supply on to separate the heat sources?
You should try a website in the source link for further information regarding case modification, I've used them before and they are very comprehensive There is a solution as to your predicament, and that is to change the stock heat sink fan for your CPU and Graphics Card Cooling Fan with an aftermarket version which should cut your temperatures tremendouslyDepending on how big your computer case is and how much internal space you have for the modificationsOn all of my PC systems, I use a Noctua branded aftermarket CPU coolerMy latest Sandy Bridge build with an i5-2500K, I use a Noctua C14 cooler on the CPU and an Arctic Extreme Cooler on my overclocked 512MB HD4870 Video card which has greatly reduced issues of heatIf you are getting PSOD (Pink Screen of Death), it is your graphics card and you need to change the stock cooling fan to an aftermarket versionIt takes a bit of tinkering but it is well worth the effort if you do it right Approximately 15 years ago, a manufacturer which is still around today; known as Lian-Li made all of their cases, especially the PC-60 series with a full aluminium chassis including their internal structureSo in answering your question; yes it is safe; but it depends on the design and ensuring you don't have any sharp edges and you may have to use a rubber edge to protect yourself from cuts and scratchesLian-Li does this also with their cases, you should perhaps visit their website for some inspiration You might also consider cable management, use some cable ties and some electrical duct tape to increase the air flow inside your computer case by taping it around the edge of the case (internally) including your SATA and IDE cables and power connectors.
It is a little hard to determine from the photo, and not knowing specifically about your application, whether this bearing could be usedA lazy susan bearing is designted to bear shaft end load, not side load, and it is difficult for me to imagine how this could be applied to support a side load, instead of a base load for shich this is designedIf you are designing this apparatus, can you design the hub to ride on a small diameter shaft? You would only need about a 1/4 diameter shaft to support this loadA small bearing for such a load would be only a few dollarsAn inline roller skate bearing would work.
