If anyone is interested I have a surplus of PC case fans that are free to anyone who is willing to pay the postage. See pic below. They have a standard 3 pin conector on them and about 350mm of wire they measure 80x80mm are 25mm deep and run from 12VDC @240mA. I can provide screws too if you want just let me know. I have about 15 avail at the mo but more will come. The intention is people are welcome to a few each so its fair and they are first come first served - so dont ask if you can have them all - cos I will tell you where to go .
PM me if interested.
Rob
PS I forgot to mention They are brand new and unused.
