Hi all - So, while I'm a Mac guy overall, I've always kept a PC for proficiency and gaming. Lately, I'd been playing World of Tanks on my iMac via Parallels, but WoT's latest update requires DX10, which Parallels has spotty compatibility for, and it's not working. My current PC is a 2.5 year old Dell XPS 8100 with a 2.8 ghz Core i7 and Radon 7850 video card. It works well, but it's vacuum-cleaner loud when playing any game, and the full-size case is a giant hassle when I want to move it. So, I'm looking at building/buying a gaming PC in compact case. Here's the article that I'm working off of, though obviously I'd use more-recent components. http://www.pcworld.com/article/241623/how_to_build_a_compact_gaming_pc.html or... I can just get the XBOX-sized Dell Alienware x51 for $1049, with i5 and GTX660. Quiet, super-compact, performance should match or beat my XPS, in about 1/5 the volume, and reviews say the box is super-quiet, which is VERY important to me (now that I've lived with a computer that sounds like a shop-vac when you launch a game for a couple years). I'm throwing down a challenge to all the PC guys who say they can beat the cost/specs of what you can buy pre-built!! Here's my goals: I'd like to keep the size/volume of the case to well under a cubic foot - the X51 is roughly 13x13x4 inches. I want to go with ivy bridge i5/i7, GTX660 or better level performance, and all for less than the $1100 the X51 will cost. Thanks!
