Budget HTPC Build

Looking to build an HTPC/Media Server on a budget. No gaming. Mostly media sharing and online video (netflix). I would like to keep the price below $600 USD for the hardware. Here is what I have so far:

nMedia PC 5000B Micro ATX case - $80
Corsair CMPSU-400CX Power Supply - $50
Gigabyte GA-MA785GM-US2H mobo - $80
AMD Athlon II X2 250 Regor 3.0Hz - $76
G.Skill 4GB (2 x 2GB) DDR2 800 - $74
LG Black BD-ROM Combo Drive - $130
Two Western Digital Caviar Blue 640GB - $140

Total = $630

I want to setup raid for the two hdd's and may add a video capture card in the future if I can figure out how it works with DirecTV satellite. I will definitely use Windows 7 when I get my hands on a copy.

I have only built one computer, and that was 8 years ago, so any input would be welcome.
Thx

The prices don't seem to far out of line to me - good build. Also, props to r_manic for his posting rampage (pretty much every post that is visible on my screen says last post by r_manic)!

I agree about the RAID cooling concern, but if you need to stick with micro-ATX, check this case out:
