I did it by myself. I really had no other option. The monitor fits in and out of the back of my cabinet. If you check out my site you can see how the top is bolted onto a wooden crossbeam. I have it set up so that even when the monitor is unbolted, the weight of the monitor holds that crossbeam back so the monitor won't fall out. There is also a groove that the front lip of the monitor fits into preventing the bottom from slipping out. From there it's a matter of leaning the monitor forward with one hand, and pushing that crossbeam up toward the top of the cabinet. I lift by the two metal frame bars and get my hips up there to rest it against. I've got the D9200, and I had to set it in and take it out probably 15 or 20 times trying to figure out how to mount it at just the right depth and angle. That things an 85 pound monster. I imagine it depends on your size and sanity. I probably wasn't as safe as I should have been.
