Shamelessly large. It can fit the biggest screen. Our TV, used and huge, has got to be the heaviest set I've ever had to heft. Its perch, currently recycled plywood, but soon to be 3/4" birch plywood, is 40 inches off the floor. The Tannoy monitors fit in there with room to grow if need be (I won't need it!) The rack spaces are not all taken. For the party on Friday, the top will be done, the cable holes will be cut and the trim installed. We'll also replace the tv with our turntable, a wood/metal german affair. Cheap thrill.
