Any recommendation? What fire/heat resistance material?

Titanium.

But if you happen to be out of Ti, cardboard is nearly free and easy to work with.

nice

honestly, any paper material is fine

unless you have a really crappy PSU, nothing can really catch on fire

Good thing I have some titanium sheet around. It should be somewhere next to my plutonium storage :lol:

Anyway, thanks for clearing this up :)

If you want something a bit more hardwearing then sheet Al is commonly available and pretty easy to work with.

I use foam-board. It's trivial to work with (all you need is a craft knife), sturdy, light and thick enough that you can bevel to at corners (which if tough with something like cardboard).

Oh, and it doesn't conduct electricity either, so if it touches something electrical...

Is there any kind of adhesive you would recommend to use with it? I have a bunch of alternatives available, but haven't decided what to try yet.

would you also have any cutting techinques?

I cut up some old foam board, the end result was not pretty

You can also use styrene, as recently mentioned in the Quiet and OC Pentium D arcticle, and originally mentioned here.
You can cut it by making a line with a hobby knife and cracking it, you can then bevel the edges :wink: with the hobby knife, and you can put bends in it by heating it up with a hairdryer in your desired position and holding it until it cools down. Just make sure you get the right glue, the dude in the hobby store I went to sold me the wrong one, luckily I didn't actually need it for my mod.
This stuff is good because you can get very professional looking results (look at the abovementioned arcticle), although it does take a bit of practice to get something that looks that good, as I have noticed :lol:

I've been using "Loctite All Purpose Adhesive" ... so basically any bog-standard household glue I reckon! I have to say that my choice may not be totally ideal, because the solvent in the glue has a mild melting effect on the foam ... but it's not bad enough to have made me try anything else.

I've never tried it with old foam board (presumably the foam goes dry and dusty??). Otherwise, sharp craft knife, steel ruler, a good surface to cut on (eg. a thick piece of cardboard), plus care and patience.

Bevelling is more of an acquired art, and not strictly necessary, I do it because I'm a fuss-pot! :D
