I have done a few of them.

Fairly easy to mount. Just make sure to take your time measuring everything. One of the calculations you need to account for is for wall plates and AC outlets. Just like all their other Synergy and Chameleon pieces there are aluminum post on the front and backside of the unit. That piece has 5 rear posts, three of which you need to measure for (located in the middle of the unit). If you don't account for them you could end up blocking them with the posts. The good news is that you do have a little play with the horizontal shift once it's up on the wall.

The other issue is that wire management can get a little tedious, especially when there is a lot of gear going in it. It's tough balance between making it aesthically pleasing and serviceable.
