very nice case
i hate tell that how rad is placed is big air trap when coolant level drops leaves no heat transfer from less contact to tubes. best move the rad with fans blowing outward of the front corner of case with bungs up and move 3 fans to the top of case bllowing inward also turn cpu 180° so that can be self priming and 2 bottom fans blow inwards.
oh forget to say get a fan cotrollier that has 4 channels and min, 1 amp per channel note your AIO fan is 12V DC, 0.23A (2.76W) = x3 .23A = .69 Amps gang them parrelle, do the same with 3 upper now formally front corner and 2 lower fans case fans just check watts rating per fan convert to amps, stay within ! Amp by 10%.
also the rear fan blow inward after all done use a inferad temputer gun an check heat pattern and adjust fan speeds
