Details are in the wish list, but it's...
Lian-Li PC-60FN all-aluminum mid-tower case
ASUS Z77 motherboard
Intel Core i5 2400 Sandy Bridge
Kingston 8GB of DDR3-1600
ASUS NVIDIA GTX 560 Ti 448 cores
Western Digital Black 500GB
SeaSonic M12II 650W (53a of 12V)
ASUS optical drive/burner
That's a better case, comparable components, and cheaper at $981.92 before shipping. It's cheaper because I didn't include the OS. On that note I'd really recommend buying a "retail" copy of Windows 7, not an OEM copy. The retail copy lets you transfer it from one PC to the next. If you upgrade a motherboard or transfer to a new PC you wouldn't be allowed to use the OEM copy on that new motherboard according to the license. That said, many people are still getting around it by calling in when they activate an OEM copy of Windows on a new PC/motherboard. But just a heads up on it.
The 7870 is just a little bit faster than the 560 Ti 448, and it's a lot faster for anisotropic filtering, but the 560 Ti is also less expensive. You could go with a cheaper case ($50 vs. $100) and put $50 more towards the video card for a 660 or even more for a 670 if you went NVIDIA. But it really depends on what resolution you're gaming at. If it's HD (1920x1080) or less, a 560 Ti and a 7870 is fine. On that note with a massive cooler like the ASUS card I linked in the wish list, you can overclock it to be comparable with the GTX 580. But since the OP doesn't seem like the overclocking type, we can skip that point. And that's why I didn't add a 3rd party cooler to the CPU either.
It also matters how long you want to keep your PC to upgrade it vs. ditching it for a new one later. If you don't really care about upgrading, a cheaper case and more expensive video card is better. If you want to get a little more life out of it by upgrading down the road, you'd want to invest more into the case, power supply, and motherboard like I did in my build.
