These are the plans for my 6 tank rack. I actually already built it with a few modifications but dont have a working camera. I choose this style because it is rather strong. Looks weren't as important but it could easily be faced with something and trimmed out. If i was doing it for show I would have turned the 2x4 and notched them out. You may be more inclined to use 4x4s with the 55s.... Mine is nothing fancy but rather functional. I wouldn't want much less clearance on the tanks, however. Ill get you some pics if i can borrow a camera
