I don't think Asus cares to be honest, I've never had to request support from them but don't rate them very highly either.
My operating system will be Windows XP Professional x64, the operating system that is based on Windows Server 2003, just the 64-bit version.
As for CPU, I have the Intel Q9550 2.83GHz, which I'm aiming to get up to 3.6GHz. Thanks, I'll stick to the RAM I have, it will go up to 1700MHz I'm sure, pointless to buy 1800 speed RAM and run it at 1700MHz, just an un-necessary expense.
