I know - Ive a dedicated audio card I'd love to move over to a new build but can't see that being possible with mini-itx, though would like a build for the below case as it's, imo, totally awesome:

Read the rules. If an acronym has a decent chance of being misleading, spell it out.

Are you going to be taking it to conventions? That's really why you build these things in general. Like the bring your own PC thing at PAX for example, otherwise, I don't know if it's a good idea at all. >.>;

Size doesn't matter as much if you are taking it to your friends' if they don't have like 5 story buildings or anything.

Yep I'll be hauling it around. For sheer convienance purposes, and asthetics (would work with my HT setup) I'd like small & sleek. Otherwise I'd just go down the Corsair 550D SilverArrow route. 

Then how come PSX is allowed as that acronym makes no sense to anyone outside of the US? 

I'd say if you really wanna be nuts, just get one of them Steam Boxes lol :D

go on steam, click on the game, you can read the minimum requirements on there

Don't let them fool you - the game is seriously CPU intensive. You're looking at really a GTX660 & a 5770k for decent frames. It is a great game though. 

i really dont know much about PC, but i was considering downloading this game so i looked it up on steam. saw the minimum requirments on there. though my PC is pretty good so i wont get fooled
