"They," you ask?
I've now got 6 pentium-3 500's. A friend had them, dreaming of his own render farm, but he lacked the space for them.
This leaves me with a couple issues... I need to obtain some cheap displays (someday, data projectors). And I need to improve the cooling in that room. It is already way to warm in there in the summer (leading to the premature demise of one of my SCSI drives).
So, two compacs, two dells, and two franken-boxs. And then my main box to rule them all.
On second thought, I might make one of them a file server, and another a dedicated webserver, so I can reboot Akira without guilt.
