Love this case so much I ordered two more. The construction was easy and everything fit with such precision. My only problem was one of the Delrin side clips broke. Due to the precision of the cutting the clips need some additional force to be inserted and could snap the legs off. I suggest adding a couple, maybe two, extra ones.
Case is easy to put together & well done. The switch & clock-line hole lines up perfectly with the board. Fit is tight (no wobble) but not to the point that it will break anything. Makes the uISP really a polished, finished product that will stand up to being tossed in a box or cluttered desk.
