This one:
Asus P5K-VM Socket LGA775 motherboard - Misco.co.uk

They were pretty much all different versions of the same board, or different stores.

Yeah... someone posted they could not find it in the UK-- no big deal-- I just went looking-- cause I know Asus products to be among the best...
I have a P4P800 Deluxe thats about 5 + years old now. Never a problem with it.

ok so now i will buy tht motherboard and the rest

hi im geting confused so instead of building i think im guna just uby a pc unless someone can give me all the links to the parts to build a pc also i need a fast modem cuz i create servers thanks

Direct links to each part have been made in this thread. The modem isn't part of the PC, it's a completely separate piece of hardware which if you have servers may require an ethernet switch system, and your speed limitations are that of your ISP and not your modem.
