Old cell phone chargers are a good supply also. Probably have a few of those laying around. Used a 8.6v one for something similiar. Cheers

thanks all you guys for the great info and tom i got all the parts that you listed on your website to build your own tower cooler hahah. i have a fan with a 3 speed option so i will put it at the lowest setting so its not so loud
Great, I have complete how to instructions on the kegkits.com web site so that people can read and build their own. Not everyone wants to buy a complete & ready to install beer tower cooler.
Here's another source for power supplies that are pretty cheap: http://www.sciplus.com/category.cfm/subsection/13
One of my cell phone chargers were 12 volt. I used that for a cpu fan, also 12v. Worked fine. The fan didn't move a whole lot of air though.
You don't need to move a lot of air, you only need to move enough air to keep the beer shank inside the tower cold.
You could always do something like this...
Where to put the cooler I actually built 1 and it froze my beer overnight 18 degrees
