I second the Hard Drive magnets - my kids have been using them for years to hold up things in their school lockers.
The CD-rom/dvd-rom optical drives also have smaller magnets in the read/write heads.

The Hard Drive magnets are an odd shape and the optical drive magnets are usually rectangular.
The HD magnets can be hard to get off the metal bracket as they are glued on. The easiest way I have found to remove them is too bend the metal backet with two vise grips or similar and the magnet pops right off.

The older the HD or optical drive is, the larger/thicker the magnets usually are.

The HD and optical drive magnets are rare earth magnets.


My two bits...

I used rare earth magnets from Lee Valley.  They come in various sizes and the power of rare earth magnet is unbelievable.  You can also buy attachments for them so you can screw them to things.  I think many science or hobby stores also sell that kind of magnet.  Scrounging however for regular magnets sounds like fun too.
