When we made ours, we did not attach the ends to the sides at all. We glued/stapled the sides to the bottom, then glued/stapled the corner gussets on the top. With 3/4" sides, and 7/32" (slightly thinner than 1/4") bottom and gussets, it is very stiff and strong, and only weighs 13 lbs. The 7/32" bottom can flex a bit in the middle, but should have no problem supporting the electronics, as well as heavier stuff near the edges.

If you can get some 1/4" and 3/4" plywood, I strongly suggest you build one similar to ours and see how you like it...you might be surprised how strong and light it is.
