They look sweet :-) I'm interested in the config, is that a server PSU with breakout above, motherboard on the right and acrylic on the top and sides to channel airflow?
Yup, that's the basic layout - I put the SSD on the top also, so I can put a full-size board on the right side... DPS2000-BB with Optimizer breakout, 2x 254MM fans, and acrylic on all sides except the front and back - so the air is channeled through. I tried closing the front around the fans, but it actually made airflow worse as it would tend to pocket hot air in the front... If you search around, I think I put up some thermal images from different configuration I tried.
