My frame is from 2x4s and I put wood around it. Let is open from the end as well to get access to the sump, Or use maybe something larger on top than a 2x4 so that the font can pretty much be doors with no bar in the middle. I chose support in the middle with two doors and access from the side to slide the sump in and out. Q tank would have to be small or separate, but you could get a 10-15 gallon in there with the 29 gallon, I chose a 30 gallon sump and have room for a 10 without much else.
