the cpu has the h60, and the gpu has the h55. i know they're basically the same, but i decided that the h60 was very slightly better so i got that for the cpu. NZXT's gpu bracket only supports the h55.
the acrylic cost around $70, and i don't remember how much the aluminum cost. total cost i spent on the case i estimate around $90.
sorry, i don't have any pictures of the build process, or even any that really show the construction very well. i bought 6 sheets of 11" x 11" x .25" acrylic from tap plastic. i figured out what layout i wanted inside the computer (motherboard on bottom, power supply above the cpu, a fan above the back of the gpu, and two fans on the "front" of the case), and then figured out what i needed to cut out of the acrylic. i cut holes for all the fans, all the IO, the power supply, and a little tiny one to mount the power switch. the .75" aluminum bracket was cut into mitered joints all around. the holes in the bracket are done with a .25" bit, then a little counter sinking. the holes in the acrylic are done with a smaller bit (3/8" maybe, i don't remember) and then tapped to .25". the tap worked extremely well, much better than i was expecting, and got rid of the need to figure out a way to make captive nuts on the inside of the case.
the motherboard standoffs and drilled and tapped straight into the acrylic floor. also worked much better than i was expecting
the power supply is mounted with a little strip of aluminum drilled into the back wall, and then it sits on a little chunk of extra acrylic that i cemented to the adjacent wall.
i had originally planned on mounting both radiators on the front wall of the case, side by side, with the radiators on the inside and their respective fans on the outside blowing in. the third fan would have been at the back above the gpu as an exhaust. the front of the gpu turned out to be too tall for a radiator to be mounted above it, so i had to move that to the back of the case, and the exhaust fan above the gpu.
speaking of air flow, there isn't much. hooray for water cooling.
there also isn't any cable management. i don't have a problem with it right now, but maybe one day i'll go through and clean it up
the water cooling is fantastic, even under load i've never seen the cpu over 50C, and only seen the gpu over 50C once or twice.
