I'm not promoting eBuyer or anything, other good shops I've used before: Dabs, Savastore, Chillblast. Delivery would likely be £8, seeing as my recent order included two ATX tower cases and it was £8.
Also note: I've not researched any of these parts to see how good/compatibe they are.

Edit:
I just saw you would like a better graphics card, so here's one:
Point of View 6800GS 256mb TV/DVI PCI-E
http://www.ebuyer.com/customer ... WV3&product_uid=99318
£116.58 ex.VAT.
This takes the total to £584.73 ex.VAT, £687.06 inc.VAT.
I didnt include that crazy floppy/multireader thing, and I also wouldnt advise two optical driver, unless you copy stuff like CRAZY! I doubt anyone needs to write to DVDs! and 160GB HD is rather a lot also; you can easily get a second one at a later date when necessary.
PS: If I'm doing anything wrong/disallowed by posting links to a shop on this forum, please let me know/delete them.
