Right. After realising that I should to make a profit from this I've fiddled with the build.

Here's an updated list:

CPU: Same

Motherboard: Gigabyte GA-EX58-UD5

RAM: OCZ Gold 6GB (3x2GB) DDR3 PC3-12800C8

Graphics: VTX ATI Radeon HD 5770 1024MB

SSD: Same

HDD: Same

PSU: Same

BDRW Drive: Same

Case: Same

Cooling: Same

Monitor: Asus GD245HQ

Other:
NZXT Sentry 2 Touch Screen LCD Meter (Same)
Cheap eBay 2.5" to 3.5" drive adapter bracket
Standard SATA cables (He wanted a red theme as opposed to a blue theme. UV reactive cables in Red are expensive on eBay)
eBay Red Cold Cathodes


This leaves me with about £180 profit.

After a quick google it seems that the only difference iun the motherboards is the omission of USB3 and SATA3.

As for graphics I've explained that a single more powerful card is a better than two low spec cards. I've told him that in future he can add another card if he wishes. All is well in the graphics department.

As for everything else I don't see them making much difference. A bracket is a bracket and a cable is a cable. Unless anyone spots a mistake in my spec list it goes to him tomorrow and the parts get ordered.

Lets just hope it all goes well.
