Looks pretty cool man, I dig the spots where the monitors will go, quite ingenious actually. I just wanted to ask though, noticing your model, did you factor in the thickness of the pieces of wood? They are all flat in that model so just wanted to point that out in case you didn't realize. This is one I designed in Sketchup for myself:
Which is based off of the core design of the desk I have had for years, which I modified last year to have a rack shelf like the one in that design. However, the current rack is 90º vertical, where this new design puts the rack at a <45º angle, putting my iMac slightly lower which would be more comfortable. Plus the new one is wider to accommodate rackmount hardware on the right.
Anyway, not to derail, I apologize haha. I vote for building it yourself, you truly get what you need, I never felt like pre-designed desks would work for me. And besides, unless you get something ridiculous like an Argosy, where usually people are designing the room
around the desk, no reason not to build your own, IMO.
