I hope to experiment with PXE booting,
and I'm also interested in the Oscar cluster install project.

I think they need small 150W power supplies, if you have a mains
PSU in the case.

I've jsut ordered a Cubid case, which takes an external power brick,
so should be very quiet.

It might be fun to think of racking several mini-ITX boards together in 
a case, in that case (no pun intended) you would maybe homebrew a PSU.

Another interesting way to do things, in a co-lo environment, or
a server room is to get a 1U case.
>From the bulletin boards on Linitx.org, you might be able to squeeze
four mini-ITX into one 1U case. The 1U PSUs are 22 UKP each.
But I don't really want rack mounts in y spare room
(actaully, that is a lie. I really do.)
