ok so its this simple, I am going to buy a new computer and I want you oh so lovely people to help me build one, if I list a few specs would you be able to go out there and go to the tecie website and get me a quote and if possible a link to the said computer.

Here is a list of what I want in my computer:

3072-4096mb RAM this is the most important feature for me... im fed up of forever being slowed down so I want a bucketload of ram

Pentium QUAD or DUO core, would prefer QUAD but ill settle for DUO

A nice shiny graphics card, I quite like the ATI range atm, dont want anything with yuki turbocache graphics.

500gb HDD, not really nessisary but the extra space would be nice.

thats really all I want in my computer oh and as an after thought if you could make the OS XP id be grateful, I live in england so I dont really want to be importing anything from america and with reguards to a price range I want the above at a low as possible price just dont go too wild ok? many thanks in advance!
