They are low yes! and supposedly AV units from Wayfair about 8 years ago, you could get matching units that go further up the wall with it - think shelf units etc.
But I like them as they are low so it doesn't feel like they are taking space up visually in the room.
Its my old iMac from 2011, which I just use for media with Plex now.. I don't even use the keyboard lol, it just has stayed there as use my MacBook to control it - prob can put keyboard into drawer below lol. Just never thought of doing it to now ha ha. the only time I have ever used it if have issues with network connection. So useful to keep at hand.
I was looking at. their site yesterday couldn't see the exact same ones. But they have lots of low AV/media units... Just search media units or tv stands - its actually 3 units next to each other as is just under 3 metres wide in total.
