After buying an fairly expensive i7 NUC unit, I decided to buy a case and not just throw it in a bag like the one it is replacing.  Selected this one and am generally happy with it.  It has a very well fitting location for the NUC itself.  Only drawback is the space for the power adaptor does not come close to holding my adaptor.  It is a 130w adaptor (presumably due to the i7) and would not fit.  I ended up cutting out that foam (10 seconds with a pair of office scissors and looks fine), and now I have the adaptor in the left-hand side of the case and the NUC inside its foam on the right-hand side.  One thing that actually makes this better in some ways is that a case with a spot big enough for my adaptor would probably be larger overall, and this case is optimal in the sense it is the smallest size that will hold the adaptor and a cushioned NUC.
