Yay another giveaway!
My favorite items has to be the Antec 1100 V2 Computer Case because it's basically got all that you need from a case. 9 expansion slots which is a excessive for a "mid tower". Lots of cooling options being able to fit a massive air cooler or in this case (ha!) the 240 rad. The side fan spots for spot cooling the gpu(s) (pity the could design the window better around that though). And of course the side window to view the sexy computer bits, also it looks good without being cheesy or tacky.
