The list of parts I recommend are below. https://pcpartpicker.com/list/KmZKsJ
Thanks very much for putting this together, this is giving me some good ideas. The LED stuff is very cool, I'll definitely give that some thought. Also see below for some other thoughts.

As for cooling an AIO with minimal size will reduce the need for a larger case and keep the weight down.
Hmm -- Amazon lists the weight of the Kraken X31 as 2.73 pounds, and NZXT lists its noise as 18-34 dBA. Whereas for the bequiet Pure Rock Slim (an air cooler), bequiet lists the weight as 0.36kg (0.8 pounds), and its noise as 13.1-25.4 dbA. Is there something I'm missing for how an AIO liquid cooler could be better in my scenario?

For a clear case tempered glass adds considerable amounts of weight, but the only other options would be Plexi, which is not safe or sturdy what so ever. So the smallest size tempered glass case will be the best option there.
Ah, interesting! I didn't consider that tempered glass would be heavier. Okay, what if I do away with #6 above -- what if the case doesn't have to be transparent at all? Could I get a much lighter and quieter case?
