Any tips on scoring cheap rackmount gear? Chassis, shelves, old switches, etc. I imagine plenty of offices give this sort of stuff away, but I'm not really sure where to look. Craigslist and Facebook ...

Anyone know of a good online reseller of GOOD cheap 1U or 2U rackmount cases? I just want the case and the ps. (fans are okay too)<P>Any ideas? I need to be able to order it online and have it ASAP.
