This AIO has the worst designed bracket I've encountered. No tensions screws, a cheap plastic part that's responsible for holding the pump on top of the CPU, and for some reason Lian Li decided to make both the backing bracket and the mounting screws female, connected by a double ended screw with different thread sizes on each end and one end hollow with a hex interior meant to be used to screw into the backplate. The hex part strips extremely easily, a reverse threaded tool seems like it would have been cheaper to include and much more effective. The plastic bit covers the only section of the screw that would be useful in unscrewing it once the hex thread is gone. The lack of tension springs, and the overall design of the double ended screws, make it extremely easy to over tightened the pump, and very difficult to remove the bracket if you need to acces the CPU for any reason, like checking for damage from overtightening the pump bracket. Most confusing is the fact the mark 1 had a perfectly well designed bracket with male backplate and tension spring equipped female screws on the pump side. There was no reason for this change, and the entire design suffers greatly for it. The fans are near silent, the pump pumps, and of course being Lian Li the entire thing is beatiful. If it weren't for the confusingly horrible bracket, and the less than ideal software, I'd be in love.
