A PC in this case is indeed very quiet in operation, its appearance is sleek, and it has some great features - to mention two, memory card and USB 3 and USB 2 ports available at the front without opening the door; and the ability to use a hard disk temporarily in the slot in the front, which is great for back-up (or even extracting your files from the previous PC). But I gave a lower 4-star rating because of some problems in assembling it. For example, one of the side panels was fitted so tightly that the only way I could get it off was by prying with a screwdriver - not good! Worse, the layout of tapped holes for the motherboard fixings did not provide all required for my mobo. Worse still, one of the holes that did line up turned out not to be tapped, so I had to take the mobo back out and tap the hole in the case, with the risk of tiny bits of swarf (i.e. metal cuttings) then being loose in the case. These things, together with CM's unconventional position for the PSU, meant that the build easily took twice as long as usual. I have built many PCs and this is the first time I have experienced this odd combination of excellence and shoddiness in a single product.
