Hello all, I'm currently looking at parts to get for my PC, which is running off of some older specs. This is my computer (with a few modifications) http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01969947#N96

MY modifications to it are the graphics card, which is a Sapphire HD 7850, and a new Corsair CX600 600W.

I am looking for a new processor and motherboard, along with a case to go with it to use the most out of my 7850. I've been looking at the AMD 8350 processor (i'm pretty much set on this), and was wondering what motherboard and case would go well? I plan on going on black friday (in Canada).

Here is what I've been looking at for a MOBO Gigabyte GA-990FXA-UD3 Socket AM3 AMD 990FX SB950 Chipset

and the cases in question (wondering if they have good ventilation, etc) I've been looking at Thermaltake Chaser A31 Gaming ATX Mid-Tower Case Corsair CC-9011011-WW Carbide Series 400R Mid Tower Gaming Case

My price range is hoping to be at around $300, under $400 (the AMD Processor is 159.99 tomorrow, so that is okay). I am just hoping for a good motherbaord to go with it, and a case that will fit it all and have good ventilation as well. Please and thanks if I could get some help!
