i'm making my own as we speak--if you recall, a couple weeks ago my buddy camaro found a link to a DIY overflow box....me, being cheap, decided to make one--i was going to do a detailed post, but i lost enthusiasm
all i have to do now is cut a couple more pieces of pvc and secure the two ice bins that are serving as overflow boxes (not as easy as it sounds)...and then i have to figure out how to get this thing running without having my pump run dry or spill a lot of water on the floor
