New thin client Edubuntu lab

I would go for fanless clients though, if you want to use real thin
clients to avoid too much noise.

we have a classroom where the switch makes such a noise, that it really
disturbs everybody.

you really want a quiet classroom when there is nobody working on the
computers. such as when a non-computer class uses the same room.
otherwise nobody will be able to concentrate.

for the server I would go the same direction. as described by charles:
fast ethernet, raid and dual or quad core. I built a quad core machine
becuase it was only little more expensive than a dual one.

I have also built in a seperate drive for the home directories. makes it
easy to backup that data only.
