[K12OSN] Which server would you prefer?

IMHO, I don't think you're going to gain much if anything going from a
P4 down to a dual P3.  I would highly recommend searching for a used
server, Poweredge or Proliant.  You can get something pretty powerful
for not a lot, particularly when you consider that a new LTSP server
essentially means a new lab.  My first LTSP server was a quad p3 800
MHz PowerEdge I had purchased myself for under $500 off EBay, and I
ran 20 clients off of ok.  When that died, my district let me purchase
a quad p4 2Ghz that was only $1200 and it was like getting 20 new high
powered machines.

I think if you hunt around, you can find a server class machine with
MEGA power for well under $1000.  If you're doing this for a school, I
bet someone in the community has a server they've recently
decommissioned that would be better than what you're using now.

I do believe more processors can do LTSP better.
