1.5" on my 240g, and I'm kicking myself for it. I want to put my Vortech's back there, but can't without cutting into the sheetrock.
If I had to do it over again, I'd use the depth of a vortech wetside + 1/4". That'd give plenty of room for anything from pipes to wires to whatever. I think that's 3.25" total, but check me.
