for the ram just choose the corsair xms3(£65), cheaper, same **** different package lol
Well with the USB3 on special offer it's £17! I can't for the life of me see a difference between them. They have a slightly different audio chip and slightly different placement of some connectors on the board. That seems to be it.
It's perfect for your budget, add 2 viper fans to that Megahalems though and use some MX-3 or MX-4 paste then you are set.

or either the ud4/5/6

. But then you've gone for some pricey fast RAM, the mouse and those pricey fans. I guess it's up to your mate what he wants. Personally I'd think about saving a bit on the mobo, ram etc, and work in SSD or a more expensive shiny mouse/keyboard for example. But then they could always be added later. Oh, and if you're gonna get the UD4 - get the UD5 instead for the same price!
