Silverwind,
It is currently just a CP, but it is bolted to the desk in the picture. The CP is sixed the same as the one in Lusid's plans. I intend to build the rest of the cabinet this summer. My intention was to have at least two panles. Unless I change directions and build a copy of 1Up's cabinet.
I placed the blocks of wood so that it is a very tight fit. To open it, you have to grab the front edge and pull up hard. There is no reason it should come up during rough play. I did design it with the pesky little relatives in mind.
