I did a custom build with a canopy, I used it for a week and i destroyed the thing, seriously. It was a total pain to work around, having to get in and out of the tank all the time was a mess. There are benefits, specifically in regards to your lights and having more options with placement. I ended up with a rimless tank anyways and thus a canopy is pointless, again IMO. You can always bend conduit or use ceiling or wall anchors for your lights, unless you like the look of the canopy, then rock on :cool:
