Some of the flexibility issues mentioned are why I wish more manufacturers would just provide a case full of 5.25" drive buys. I got myself a cheap case by MS Tech for £30, but it's about the same size and has a 9x 5.25" drive bays but, surprisingly given the price, comes with a heap of plastic brackets you can screw into the bays to adapt them for either hard drives or fans/radiators. It even has quick-release brackets for every bay, and that fit pretty well (well enough I'm not bothering to use screws).Other than those kinds of touches the case is cheap, but it doesn't look too bad and also has a gap in the upper case where you can fit slimline fans, which I also liked.My point is though that given that a cheap case can do this I don't see why high-end cases can't do similar with more robust drive bay adaptors. For example, fan/radiator brackets that have rails for sliding 3.5" or 2.5" drives into, this way you can have maximum flexibility and minimal fuss, and the case design is much simpler; just give them rubber washers or whatever and you can keep the whole thing quiet too. Plus with 5.25" drive bays the whole height of the case you can move bulky items like an optical drive to the bottom of the case; I know it seems a weird place to put it, but you usually only have a PSU down there anyway, so it's not really the best place to put your intake fans anyway, meanwhile an optical drive should run just fine down there.It's the same with cases that don't offer quite enough space for fans and radiators at the top; at least with this case you could probably get (or create) a fanless radiator to mount in the upper part of the case, with fans of your own inside to blow the air through.At least this particular case in the review has plenty of cable routing options, that is by far my biggest gripe on otherwise good cases. That said, I really don't like the styling of this case much, and I just don't think it's worth the money given how awkward it sounds to reconfigure; a little extra effort from Cooler Master could have solved those problems.
