Okay, so thanks again for everyone's help. I'll probably be ordering everything by the end of the week.
Here's where I'm at right now:
wishlist.
If that all looks good, then I think my final question(s) is are there any little things like cables, screws, or other accessories that I need to order, too? For example, one of the customer reviews of the HDD said "you'll have to supply additional SATA and power supply cables if you don't already have these". I don't know what those are or if I'd already have any.
Thanks.
Edit: Okay one more question I have is would it be worth the extra $100 or so to get the 8800GTS (x2) instead of GT (x2)?
