Think about changing the order of preference at startup (between the CD drive and hard disk) in the BIOS to install your Windows! For my part, I chose windows 7 pro, and have had no trouble installing and no trouble finding drivers (other than those on the supplied CD) on the net, via TLD!
For the game, that's fine, whatever a little more RAM would not have been too much, but that's quibbling! ^^
the fan, it is best to start at a phase of the game in my opinion, remains silent!
I recommend this article for the quality / price!
