I would change the Motherboard too the Nforce 2 and not the Via KT400 board.
Probably what you where aiming at but the V inn the mobo name indicates a Via mobo, and i didn´t think thay made a delux ver. of it..
The Via board is a worse performer then the Nforces one´s.
The rest looks real nice
Well just my tought..
