This is my proposed new (and first, incidentally) build. Just looking for some advice and to make sure I'm not missing anything. Yes, I am aware that I haven't included a monitor or OS. Those bases are already covered. Also, keep in mind this a *very* budget build. The only thing I'm worried about is that the reviews say that the GPU is huge. Its a double slot. Is that really gonna be that big a deal? I'd like to keep my options open for a dual GPU setup in the future, but I don't know if that would fit.

My list looks short. I feel like I'm forgetting something. Its been a long day over here, somebody help me out.

/edit Also, all prices are from Newegg. If anyone knows an equally reputable company that can do better on the prices please share that information with me. I've already emailed Newegg customer support to see if they'll hook it up with some promo codes. Hopefully I'll get a guy that hates his job and he'll give me half-off just to spite his boss.
