That's actually a fairly common setup, known as a LackRack [0], although this one seems to be a different size/model, but maybe that's my eyes playing tricks on me.
Edit: actually now that I look back at it I'm almost positive this is the deeper lack "coffee table".
Enterprise Edition, baby! It's an official variant.
By the way, if anyone is considering deploying their own LackRack, I would highly recommend reading the installation section in the OP. It's got some quirks that are worth considering before you dive in.
I wish I'd have known/thought about that years ago when I bought a metal rack which i subsequently ditched due to space constraints.. though at that point I was young/stupid/wanting 'cool'/enough that I probably wouldn't have cared..
Ah, the LackRack™.[0] One of the cheaper home solutions for server equipment - scales nicely, too. Just like anything remotely workable, of course, it gets no industry interest.
