+1 on"Lastlight has a nice 34g great price also.
You can make a return overflow like the neo nano's have easaly you just need some glass cut on a 60 degree angle and mout it at in the center at the back the return just uses a bulk head . one other thing yo may want is 6-8 very small holes drilled about 4-5 inches from the bottome in the front glass If you use smaked glass that would be cool. I had one but it is sold localy to a youg chap how is just getting in to the hobby for 1/3 new price. The one I sold was new and unused..
