System requirements

I am concidering setting up a server for a web page and I am clueless as to system requirements. Could someone tell me the requirement for installing unix from a hardware perscective.

Is it installed with no other OS on the computer. A mini primart would be greatly appreciated !!

Hardware-wise, you don't really need much. Depending on what type of website (small personal, business, enterprise), you could go anywhere from a P133 with 64Mb of RAM and a 1 Gig disk, all the way up to a high-end server...
