aye it seems he cleared his build after he left. the only evidence of his build remains on youtube
here is the final build of his FT02
for some reason vid link doesn't work so i have to link the URL instead
here is a previous version of his build
as you can see, he did not simply build a great looking machine, he built a great looking machine with functionality in mind. he knew the 120mm rad was not contributing to the overall functionality of the system, so he tore the whole thing apart and replaced it with the triebwerk fan. most of us would have left the 120mm rad in there because it already looked great and functions well. but he just went the extra step to remove "clutter" because it wasn't adding to the overall functionality of the system. a minimalist/perfectionist approach to an elegant build. not to mention the additional step of adding the water chiller plumbing into what we know to be a difficult chassis to work with considering he had to drill through both the 4 millimeter aluminum uni-body and the steel sub-frame to add those quick disconnects. his build exemplify the philosophy of what OCN stands for IMO. maximum performance at a minimalist approach. only add what actually helps the system, and leave all the fat out of the system.
I don't think he was the 1st to do a 540mm rad, but he definitely set the standard that all other 540mm rad builds are measured against.
