I've put the Mars 5 Ultra in. Plenty of space to remove the printer cover and work around things there. Cooler is a little bit noisy but it actually makes a HUGE difference in terms of smell control, safety and temperature control (there's snow outside right now, and the enclosure helps getting the inner temp to the recommended values -and keep it there- pretty quickly (plus it has an UV cover to reinforce darkness inside). Feels of really good quality, steady, can't recommend it enough for resin printing in spaces we couldn't otherwise.
