Got the pc all put together, loop all arranged, everything done, only to realize the 28mm tall rotating 90° fittings on the gpu block will not fit under a radiator that has only 24mm of clearance. And those were the lower profile fittings. 3 weeks later finally got ahold of a couple of 20mm rotating 90's in the right i/o diameter. I love my mITX, but ACK! Can't believe I missed that particular measurement.
