Seems to be about the same footprint, but I am wondering about the water reservoir. I would not keep it outside just for algal reasons, but they do take up a lot of space. I am trying to get a 200g one into my tank room, and it won't be easy.
As far as noise goes, there's a lot you can do like isolate the pumps with rubber mounts, use flexible PVC, and a weatherized exterior door. I went even further and installed a second 2" deep wall around my tank room with the studs offset from the viewing room studs, so that the inside sheetrock is not mechanically attached to the outside sheetrock. I also foamed all switches, outlets etc. because they leak a lot of noise.
My tank room is quite noisy running a Hammerhead, an Alita 100, various other pumps, 1000W ballasts, etc. and you cannot hear it from the viewing room at all. This is an important subject so feel free to PM me for further discussion.
