This reminds me (kinda) of the people running a K6 at some horribly fast speed (like 400Mhz). They had some kinda liquid or freon cooling system.

I ran my old 486 for quite a while w/ out the case since one of the cooling fans died. However, I had a nice 10 inch desk fan blowing on it the whole time ;-) Boy could that thing sure roast a few IDE hard drives. - alex To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
