Very nice!! Thank you for sharing!! Any more pics showing how you dealt with the cabinet on the back. Looks like you snuck in between the cab and the tower nicely.
If you haven't already sealed them with silicon....your trays.....you can loosen up the screws and hold the trays up so they are even/level and not sagging....then tighten them back up.
I'm happy to see another Pro user here and I'm looking forward to seeing what you use it for.
