I originally bought one of these https://www.optimumproject.co.uk/products/pro1600f when I needed to rack some (now moved on) dCS Elgar / Purcell equipment. It worked pretty well but was tight from a width perspective. It was a pig to move around on the carpet as well when you needed to get behind it, domestic reasons mean it has to be close to the back wall.

I’ve subsequently gone the bespoke way using a local cabinet maker, which overall, has been a success. It’s not the most pretty of units but hides all the kit and was designed with the skirting board in mind so sits flush to the wall hiding all the cables (so some brownie points from the other half!).

Depending on your views on hi fi racks and sound benefits (I’ve got no view either way) I’d still go bespoke again, mine cost about £1100 all in. If I had a dedicated room I’d perhaps take a different approach and look at hi fi racks. I can dream for now!
