We have a 1/3 height wheely rack in the office that can be wheeled over to someone’s workspace, and it would be more convenient than setting up a dedicated station.

As for rack mount power supplies: HP models on ebay or the university auction are usually a decent option.

(It's so solid we've had multiple UPS and Dell PowerEdge in it .. probably hundreds of kgs, not even a small flex. 10/10 from us for the rack)
We're looking for equipment that we can fill it with to convert it to a portable lab, like power supplies and oscilloscopes that will mount to it.
The rack mountable options we found for power supplies, scopes etc were starting at ~2-6k per unit plus like 1k rack mounting kit, but ideally we were looking for max 1.5k or so.
It would not look as aesthetically pleasing or perhaps be as stable as bolted and racked equipment, but the function is the same.
