- The Obsidian 650D is a nice case but it is major overkill. You don't really need hot swap hard drives in a gaming rig, you don't really need that except in a server environment where you're dealing with huge, huge amounts of data. Go with the Carbide 400 or the Graphite 600T - you'll save about $150 which you can invest elsewhere (I'd say in a better video card like the 570 or 6970). I have the Graphite 600T and it's a very nice, extremely solid and roomy mid tower that will give you plenty of room for the biggest graphics cards, fans, heat sinks, liquid coolers, you name it.
- Go with EVGA over MSI, they're a far more reputable company when it comes to NVIDIA products. If you go with AMD/ATI, Sapphire and XFX are pretty reputable brands in that area.
- Asus DVD burners are horrible. I had one nearly explode on me. Go with Lite-On or Sony - far better and will cause a lot less headaches.
- Avoid Hitachi hard drives - Seagate, Western Digital, and Samsung are all better brands. Hitachis have a much higher fail rate than anything else you can buy.
- You also may want to check out a closed-block liquid cooler like the Corsair H100 or Antec Kuhler and see if that would suit your needs.
Hyper 212 evo I believe will be best for you. I recommend looking at Samsung hard drives specifically. You also don't need that big of a power supply. I have the same gpu and 650w is more than enough. Here's a power supply... http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I personally prefer XFX and Seasonic over corsair.
