Check craigslist for new or used hardrives. I just spotted an 80 gb Intel ssd for only $45, but you may need more space for games. Newegg links are broken, so I'll list them by model and price:
Biostar A880GZ am3+ for $59.99 plus $4.99 shipping has everything you need except usb 3.0
Asus M5A97 EVO am3+ for $94.99 after rebate for full size atx cases only; as no onboard video
ECS A885 GM-A2 for $44.99 after rebate plus $2.99 shipping; this board is am3 only (no bulldozer support), no usb 3.0, and atx cases only For experienced builders only who don't need fancy bios adjustments; I have used ecs, but many folks won't touch them.
