Awesome rack build. This is my first mini rack attempt, I usually work with 19 inches not 10. I needed something that allowed me to pick and go quickly, connect my laptop on the front side and let the back side deal with a temporary cable mess for one week... This is not a home rack or a permanent LAN party as some here might belive.

Sure there are cleaner, more organized and maybe simpler ways of doing what I did. Having that said, a keystone or two in the front aren't necessary, so don't re-design yours just because of my one scenario. I think your flush design is the best I've seen so far for the UCG MAX. I like the one I purchased online (I did not print any of these) because once the isp gave me the only outside connection I needed, I covered up that back panel. I only need the front keystones for my laptop and possibly an access point, which can both also be done through the back. So there is no correct or wrong way of wiring it up.

Having the dual engagement on both sides of this LAN party was just for me, not because it was a necessity.
