I got the pump from ebay, actually when I think about it, it was new. The rest was looking about various classified sections on forums.

Here's a quote from one that's available just now:

Thermaltake Aquarius II used watercooling kit without pump (or you can have the dead pump that came with it) - good condition, used for 12 days and pump died
£22 incl delivery

Edit: I also know of a LRWW AMD block for £22.
