I work at a company that sells refurbished computers. Mostly sgi and sun stuff but others too.
Anyway, we routinely toss out complete cases for sun systems and sgi systems (for sgi check out the octane and O2 and origin 2000 deskside for sun we have several from 1u's all the way up to the sunblades and beyond). I am putting together some random pictures and will have them posted next week. If you are local, (santa clara,ca) they would be free, if not, then pay shipping and they are yours... Otherwise they are all destined for the scrap heap.
I will be posting my bubble-gum machine mod in the near future...
