Ever accidently buy hardware on ebay?
If a bid is in the early stages, sometimes I'll make an absurdly low bid on a system so I can watch the bidding more easily. I did this for a Sun Utra 5 with 360mhz untrasparc IIi CPU, 17" sun monitor, Solaris 9 installed, keyboard and mouse. I bud $100 and won it! I couldn't believe it. Now I get to tinker around with a true 64bit CPU and OS and refresh my knowledge on Solaris... pretty cool.
In the same session I bid $45 no a PIII 667 Gateway, 512mb RAM, and 64mb GeForce2 and won that one also... .I think I'm going to use "watch item" from now on instead of making a bid I don't think will win!
If you have Software, and friends/clients that need a cheap box for browsing and office applications, you can easily slide into a pIII for under $100.
