I think in total they would come to about £550 on amazon, including shipping and windows 7
The part im most unsure about is the power supply. A friend told me that it should be good enough, but wasn't entirely certain. I think i saw it reccomended on another website, but aside from that i havnt been able to find much information on it.
Also with the graphics card, im not too sure its the best choice for the price, but I dont want to pay too much above £100.
