Meh. If I wanted a rig that was built strictly for gaming, I'd build it myself and put it inside a nice little form-factor box. Screw those giant-ass boxes - they're mostly like that so they can have fans bigger than your head so they can be quiet.
You also tend to save a few hundred bucks by doing it yourself, which honestly isn't as hard as you think. You just need to ensure that the parts you want are comaptable (this is especially so when considering what case you want - don't wanna get a case your mobo won't fit inside), and have a nice little static-safe work area.
Oh, and for heaven's sake, read the docs. That will save you so much sprockin' trouble that when you do and something weird goes down, you'll actually laugh when you realize its something you read about in the docs and can easily fix instead of freaking out. Speaking from personal experience, BTW, for both cases.
