Q: i am going to use this for vieos, internet videos ,music ......by the way this a server but can i install windows vista on it ? and use it as kidda of media centre ..it has 4gb of ram ...
A: That HP (from your other question) is designed to be a server, not as a home computer. It doesn't have a sound card, the onboard video card is very primative (it will /not/ do Aero as is) and I'm not even sure if it can use a PCIe video card. (Even if it can it's speed will be crippled.) Also, there don't appear to be any hardware drivers for non-server versions of Windows so while you could in theory install the Vista core based Windows Server 2008 and use the drivers for it, you'd have to buy a copy and the OEM version is over $600 and I don't think it includes all the bells and whistles that regular Vista does. In short, don't buy a server if you don't want to run a server, that's all they're really designed to do.
