Having a clear out at work, when I'm next in I'll drop in the following if they can be used:
* 48v unregulated PSU
* A box of heatsink fans (I noticed you guys collect fans!)
* A few variable speed fan controllers
* A bunch of wall warts
We're also going to ebay a bunch of industrial rackmount and cpci chassis and similar items, give me a shout if you want more info (will be a good price).
