The other side of this is get 3 cheap $500 machines with dual-core
Athlon FX chips and plop a total of 4 GB RAM in each box. Add a 1G Nic
to each and you have a baby cluster that won't kill off but 10 machines
when it croaks for about $1700. Save yourself the 64-bit hassle and run
32-bit on this. With the cheap box, it'll be sharing out system RAM for
video RAM anyway. Put the server in front of the teachers. Use ldap
authentication upstream and NFS mount /home dirs from a file server.

The current LTSP servers they have are all Supermicro units with Xeon CPUs. Storage capacity is not incredibly important as all user data is stored on a separate fileserver and mounted via NFS. What would you recommend for specs of the hardware? It should be usable now and be scalable to support future K12LTSP setups. I appreciate any insight you can give. Thank you!
