Hey I dropped the ball on this a little bit. Actually I was looking for this thread and for the love of geebus could not find it. Well this is the PSU I have floating around here. Its a dual rail 5VDC @ 13A and 12VDC @ 2A PSU. Fully enclosed. 12V @ 2A is not big but for sure it could help you power a few fans and maybe a pump + its FREE.

If you want it PM me your shipping address and its going your way.
