Just finished some quick tests and the results are looking good! Just keep in mind that they are in no way super scientific and should be treated as anecdotal:
The Loop was stressed using Cinebench R20 Looping for 1 hr to reach steady-state conditions.

From my perspective, the temps noise and temps look well within the margin of error and could be down to mount variance or some unbled air in the loop. As for user experience, its mostly good. The instructions were easy to follow and the machining on the block looks very good.
One suggestion is to look at a different mounting system. It is by no means difficult, but the washers sit just above the last threads on the stud, so if they aren't perfectly aligned, the can slip off easily when screwing in the thumbnuts. It would also be nice to have thumb nuts with a Philips head on the top. ITX systems are tight, and even on an open bench, it can be tough to push down and tighten the thumbscrews at the same time to engage the threads. Finally, when screwing the studs into the backplate, it will leave some space between the motherboard and the backplate. This isn't a problem because the thumbscrews and springs create mounting pressure, but to a new user, it may seem like something is wrong.
Here are some quick and dirty pics of the setup:
