What kind of material is good for resisting heat?

I'm looking to make a homemade case for the computer I'll have built within the next couple of days. I thought about doing plexiglass but my dad said that it would more than likely be too costly to even bother with. Does anyone have any suggestions?
 
Um...tell me what, exactly, in your computer will catch on fire due to the SEARING INFERNO that exists on your motherboard.
 
Acryllic/plexiglas cases aren't *too* expensive, and they're easily formed. I doubt you'd have any issues with the heat with these materials.
 
I recommend using wood soaked with gasoline as a case.
or wait ... I mean I recommend against that.

Seriously, plexiglass, aluminium, steel, and even plastics will work fine. Heck, I have seen Pizza box computers.
 
Bolt a 10 mm thick sheet of PTFE (Teflon) to the bottom of your chassis! No wheels required to make it glide across the floor. This is a bad idea on ships though.

Plexiglass is actually a very economical material.

However, my personal opinion is that clear computer cases are really dorky.




 
The only thing hot enough on your computer to catch things on fire is your CPU, and that's generally covered with a heat sink.

There are people who've made cases out of wood or fabric with no problem.

However, the following are good:

- Fiberglass
- Wood (heavy wood, i.e. burlwood, oak, etc)
- Plexiglas
- Sheet metal / aluminum / steel

it's just like showing women.....a full naket women is really nice to look at..but....the anticipation of undressing is even mroe exciting.....like if there's a pic of a chic that is in the motion of undressing...almost showing her stuff...that's more exciting then looking @ a neked chic....donno my psych teacher told me this..and i'm going to have to agree on it......

same w/ computer cases (lol)....u have a mere window...u get more excited...then showing the hold innards...😛

I could have phrased it better, but yes, that is true. 😀

Asbestos would be a good material for the case, although how you would manufacture an asbestos case or even get some in the first place is beyond me. Stone would be good too. Get someone to sculpt a complete computer case out of pumice or something. 😀
 
Use the same material as the Space Shuttle tiles.

Remember watching a documentary once and they showed a guy taking a blowtorch to a cube. He turned off the torch and in less than 2 seconds picked up the cube in his hand.

But then his case might explode upon turning the computer on. 😀
 
you could try Lexan.

Then your case would be clear as glass, also. Wouldn't that be cool? . . . unless you are a really messy wire-person, like myself. Some things are better left out of plain sight.
 
I do not think acrylic or plexi would be all the expensive.

BUT

Remember that your computer is a source of RF radition, metal cases which are properly built do an execellent job of shielding this radiation from the environment, without that protection you may well find that your system interferes with your portable phones and perhaps your TV, not good.

Also, typical plexi is a non conducter therefore you may well develope a significant charge on the case, static charges around sensitive electrions is not a good idea.

I have measured static levels on plexiglass in the 40KV range. I personally would not recommend a plexicase, unless you find a source of static disapative material (They do make it, it does cost more.... much more.) ~ 2K$ for a 4'x8' sheet.

I'm not sure if you're referring to either carbon-carbon composite or aerogel. The former seems better suited to a shuttle exterior, whereas the property(ies?) you speak of are usually delegated to aerogel.
 
I used to have a chunk of tile from my visit to the orbiter processing facility. The nose was carbon carbon. The tiles all over were ceramic with the dark black ones being a better shield than the white ones (the ones on the leading edges of the wing, tail, maneuvering engines)
