I believe it is 3/4 in. front, back, and sides and 1/2 in. top and bottom (I'll go to my shop tomorrow and confirm thickness). Top has 3 large cut outs approx 18 x 24, I'll get some pictures and will be able to e-mail them. I have never figured out how to post pictures. Have some iwaki pumps, blueline pumps, bluewave 7 ballasts (dual 400 watters) with sunlight supply pendants (the big big ones) a 75 gallon oceanic sump drilled with approx 11 holes, 55 gallon fuge. MTC dual tower skimmer. Other misc smaller items. No stand, this tank was an "in-wall" at my old hose and sat on a built in CCA stand that stayed at the old house. Have not figured out any prices yet so cant list them for sale...
