My DAR125SSDD came in last night and I can't wait for the weekend to get working on it. As some have noted, it indeed is the version that removed the screws from the door assembly. Another user posted his build with this version on his blog (could not find the original forum post) and it provides some good pictures and ideas for handle the construction:
I've never really taken on a project like this before so every little bit of advice and lessons learned I find is comforting. Also, due to a constrained budget and an impending move, I'll be doing the conversion in 2 stages where stage 1 is modifications on the door and and implementation of kegging system using picnic taps and stage 2 will be installation of the tower. Stage 2 timeframe is TBD.
