Not only did I ruin my fingers to screw the damned things, but I'm also not sure if I did it right. The tubing on some fittings comes out with an angle, which means the tubing moved while I was screwing the rings. I've got no leaks from them, but I want to fix that. Can't decide on whether I should redo it with the same tubing or not.

Btw, i'm using 1/2 3/4 too.
I know it's been stated here in numerous sections (esp the intro to watercooling thread) but I believe it bears repeating here...
Compression sleeves (the threaded + knurled part) should not
be tightened all the way down to flush against the base. The G1/4 threaded part with the O ring on the other hand should
be completely screwed in until the O-ring is either invisible or almost so - basically until tightening it more would cause damage to the block, res, rad, etc... to which it's attached. In general (in my experience at least) the gap between the compression sleeve and the fitting should be just slightly less than the width (sidewall thickness) of the tubing used. If you tighten it further you risk shearing the tubing itself which is more likely
to leak than if it's not as tight.
Because of the tightness of the threads it may take a little work to make sure it doesn't go on cross-threaded (which would make it very difficult to turn indeed and will permanently damage the fitting). In no way should the hardest part of this operation be tightening the compression sleeve... it should be pretty easy until the very last turn... and if it's really hard to turn at that point - it's because you're already done and going further is starting to shear the tubing itself.
Congrats! Looks fantastic (although the pics are a little dark to truly appreciate it in all it's glory). Great job on your panel (looks much better than mine!)
