One way I solved the multi-monitor/desk height solution…I bought a motorized adjustable height stand desk base. Got it on Amazon for maybe $170 a few years ago I think? (it was pre-covid, so can’t guarantee that’s still the price). But I just wanted a base, and then I just grabbed a piece of 6ft x 24"x3/4" laminated shelving material from Lowes/HomeDepot/any of those places. Usually not much more than about $30-40. They come in all shorts of finishes, so you can make it match your needs (or if you have an IKEA around you…I didn’t…you could get a desk/table top there for fairly cheap I think). If you want to get crazy, you can even get some laminate edge stripping (that matches your finish of course) and put that on the two side edges (only one edge comes finished in that stuff).
But anyways, take your adjustable stand base, widen it as far it says it can go, and then mount the top. You’ll of course want to keep in mind the amount of weight you’re putting on it and just make sure you’re not going to overweight what the stand is rated for, but with 3 monitors (1 ultrawide and 2 regular) mine was fine.
And then yeah, i mounted the honeycomb alpha and bravo under the desktop so I had plenty of room for monitors/keyboard/mouse up top. Then just raise the desk up to the height that fits your needs the best. That’s my two cents…worked for me, figured I’d share!
Ps. I think you can even get those laminate shelving boards up to 8ft in length…probably overkill, though, and your desk base may not be able to handle that. I found 6ft to be perfect.
