Alright so I have 400$ for everything but the CPU. I tried hard to fit a Radeon HD 6850 into this but it just didn't fit, so I just decided to go for a ASUS GTX 550 Ti. i also tried to get a zalman z9 plus in but the price is a lot higher on ncix now and will go over budget., so I decided to go for a NZXT M59 mostly because of how it looks. Corsair is a pretty respectable company for ram so I chose 8 GB Corsair Vengeance. I'm going to use my USB CD-Drive instead of buying one.
I just want to know if this is the best I can get for my budget. Is there anything better I can get for the same price? By the way can I boot/install windows from a usb cd-drive right after I build it?
Feel free to cross-search for the products I found on newegg on other sites.
Case: Good choice (see suggestions below).
Video Card: Don't settle for that. This video card is only $5 more at initial purchase and the MIR will make it cheaper ($120 total, after MIR, $135 before).
Motherboard: I tried pretty hard to find a better one than this, but since you have an AM3+ requirement, I was unable to find a cheaper one. It's a tight board, though, so make sure you cool it sufficiently.
Hard Drive: Wow, the prices keep fluctuating. That looks like the best price right now, unfortunately, go for it.
PSU: I've never heard of that brand. I'd advise against it - a PSU has the potential to fry your whole system, don't go with a no-name brand. Pick one of these - just read the reviews before hand so you know what you're getting, then pick based on reviews:
Memory: There's no reason to get that memory. Your motherboard doesn't natively support 1600MHz (supports up to 1333MHz and then must be overclocked thereafter). You can save yourself $20+ by getting this memory instead:
