Indeed. For a comp case, you could try just getting a generic case. Hey, if it looks like crap, a theif would probably think it's crap eh? Just go to your nearby comp shops, see what kindof generic cases they've got. You might wanna try to aim for a server tower since these parts will need good air circulation. Server towers are obviously more bulky than medium sized cases, so if you intend to lug it around quite a bit, you could try going for a medium case. Some have handles, but I still suggest grabbing them from the bottom as you never know eh? and with expensive comp parts like this? definately don't use a handle that comes with it as if anything broke I'd be like committing suicide. If not then I'm sure a couple other forum members would instead. I know I would, lol.
You said you'll be doing some uber rendering eh? Hmm.. I remember reading on one vidcard company that was founded by ex-3dfx company members, and their vidcards are solely for computer animation... bleh, I can't remember, anywho, the vidcard you got should work really good anywho.
