Well that was what i was thinking. I am more interested in taking the back peice out, but its the same as the front only the holes are just a little but smaller. it does seem to look like it is two pieces, but it may just be the outer facing of the stand put together there and it may be one giant piece. My thought all in all was that if I cut it out with a very thing blade and put the sump in, and then put the center piece back in, I shouldnt have any problems.
Also, as of right now, I am still starting the tank, so there isnt anything in it at all, completely empty.
