New Budget Build

Hi. A friend of mine wants help building a work computer (no gaming or movies). His budget is $400 (including shipping). And he also wants it to have a small form factor. This is what I've put together so far. Please tell me what you think.

CPU: Intel Pentium E5300 - 83.99
PSU: Corsair 400CX - 49.99 (-20.00 MIR = 29.99)
HDD: WD1600AAJS - 39.99
Case: COOLER MASTER Elite 360 - 39.99
DVD: Lite-On 24x CD/DVD Burner - 27.99
Shipping - 16.93

I am selling him used:
RAM: 2 x 2GB OCZ SLI DDR2 800 - 35.00
M/B: Gigabyte GA-P35-DS3L - 80.00
GPU: Cheap !@#$ I have lying around which I have no idea what it is - 0.00

Does this look good? Also, do you think I'm overcharging him on my used stuff? It's all in perfect condition.

Thanks in advance!

ASRock K10N78M 54.99
G.Skill DDR2 800 29.99
Kuma 2.7GHz 64.99

The rest is pretty much the same. You won't be getting the MIR ever. Also, This mobo has embedded video.

Thanks, but he wants Intel (I agree with him) and 4GB RAM.

Act fast, that Corsair PSU deal is only today.
