If you’re a gamer looking for a superior-quality computer case with all the features, consider this one from Ultra Products, one of the world leaders of innovative computer solutions: the Ultra eXo ATX Mid-Tower Aluminum Case. It’s one of their top-of-the-line cases and is built to last years of use. It complies with the standard ATX form factor for do-it-yourself users. You can even fit microATX and EATX motherboards (and peripherals) can be fitted in this chassis!
If you’re the type who will only settle for the best hand-picked components when building a computer system, but feels that buying an already pre-configured computer system is just to limiting, then it seems that you should get a barebone kit which is intended for the power user. Once you have an XFX nForce 680i LT SLI Socket 775 Barebone Kit, all you would have to do is equip it with additional input/output devices to suit your needs. Since this half-assembled platform already comes with a power supply, motherboard, RAM, a cooling system, and a DVD burner, completing the system should no longer be a daunting task.
