I think William forgot to mention he is looking at building a Thin Client 
server.

From the documentation at the K12LTSP project:

-snip-

Server 5 clients:
    *  CPU: One PIII 1 gig or faster
    * RAM: 512mb + (50mb for each client)
    * HD: ATA/100 10+gig IDE
    * Network: (2) 100/base cards and a 100base hub (8 or 16 port)

 Lab or Building Server 10+ clients:
    *  CPU: Two or more PIII or Xeon processors. AMD now has dual Athlon 
solutions but we have not tested any. (Offers?) ;-^)
    * RAM: 2gig or more (512mb + 50mb for each client) More ram = more speed
    * HD: UW SCSI drives, one for applications and one for /home
    * Network: (2 or more) 100/base cards and 100base hubs/switch (16 or 24 
port, switches are much faster with more clients)

-snip-

The info is a little out of date ( using pIII and dual athlons "now 
available" ) but the general ideas behind it are still relevant. New and 
faster CPU speeds will improve these numbers, but available memory is the 
most important factor.
