well if you put it into euros i paid about 1150 for it all.
that includes the cpu, memory, motherboard, graphics card, harddrive, gigabyte case, power supply, liquid cooling system.
i didnt buy vista, got a copy from a mate.

and this is all with the exchange rate, so im sure you would be able to get a similar system for under 1000 no problem! if you are not gona run a 64-bit operating system you dont need 4GB of memory, 32-bit operating systems only see about 3.25GB in total. So 3GB would be nice, it makes a huge difference!!!
