[chuug] What to do with some older rackmount servers?

[Alex C]

Hola-
A little while ago I acquired some P3 era rackmount servers, along with 
a rather sturdy rack. I initially set them up to be dedicated game 
servers for the LAN room at MAGfest, but now that that's over they are 
just  collecting dust in the basement. So, I am now looking for 
fun/interesting uses for them and I would be interested to hear ideas 
from the CHUUG community.

Specks:

Casper:
4x 700Mhz Xeon
~46G scsi raid 5
1gb ram
1gb nic
Gentoo Linux

Penpen:
2x 1Ghz P3
~46G scsi raid 5
1gb ram
1gb nic
Gentoo Linux

Laforge:
2x 800Mhz P3
~36G scsi raid 0
512M ram
1gb nic
Slackware Linux (likely to change)

Thanks,
-Alex
