PCSolutions411 is a Kansas City-based computer repair facility that builds and sells MacQuariums on the side. Adding the motherboard to the back of the tank adds a nice effect, and scares the fish at the same time. If you decide to do the same, make sure you keep the mobo on the outside of the tank or else you'll kill the fish while you're scaring them. As if you couldn't guess, the PCSolutions411 website is http://www.pcsolutions411.com.
