For a straight shot I think this is the nicest I'VE SEEN. (IMHO)
It's got rear support for heavier equipment towards the bottom of the bays, and it looks like a static cabinet when closed. You kind of need to give it a "reach-around" when you fiddle, but you get to hug your equipment at the same time.

Plus MA's stuff is finished the same so it looks uniform when it's all together. And they've got nice fascias-shelf combos for almost any current or older components:

And a cool search engine to look up your components:

If you've got to have a "spinner" then you should give the Avtrak a look, but it's got Melamine shelves. Kind of a "lazy susan" A/V equipment cabinet.

MA makes a spinner that is an actual rack frame, but you have to utilize rear mounts and buy shelves from MA or some other rack Mfr. (In general BGW's less expensive.)

Generic looking, but sturdy shelving and accessories:
