It is not that easy the first time. However, it does get easier once you have started. The satisfaction you get from putting a computer together is difficult to describe with words. Besides, you could sell a few of them and try to become the next Michael Dell. If all you need to do is word processing, spreadsheet, home finance, some basic windows games, e-mails, and browsing the Internet, you are an average user .
Servers are a lot more complex than any other computer systems.
Normally servers should have as high a CPU speed as possible, preferably Pentium III microprocessor with 512K cache, a minimum of 128MB memory and 9.1GB or higher hard disk drives, often SCSI along with a network adapter. SCSI hard drives are better designed for simultaneous data access and not limited to just four hard drives as their IDE counterpart. Since servers rarely deal with a complex graphics, a 4 or 8MB video card would do the job, unless it is a Terminal Server. Use a large case with tons of cooling. Well, the price tag could go up quickly.
