That is what I do at my carpentry shop. But to be honest that would make that tank, the most expensive 20 gallon tank ever but than again is custom build so that makes it special.
I dont think it would ever sell, given it would be over a grand.
custom or not, it would be too much, even for the enthusiasts here who have that kind of cash to spend... Unless it had an anti-gravity field that made it levitate, i would look elsewhere. Hehehe
