Yeah, the stock 540 fans ain't the quietest are they?
Probably not the worst stock case ever though.
I've finished the air cooled build in my 540 (barring any problems). Not the most enjoyable case I've ever used. Well thinking about it it might be up there, but I've not really enjoyed any.
I found it a bit small and awkward (although it's a small case so that's to be expected).
The USB 3.0 cable wasn't long enough to reach the bottom of my motherboard, why so short a cable, cutting costs by reducing cable length?
While it's not hard to fit all the cables behind the motherboard tray, I did find it quite hard to make them neat, especially with a non-modular PSU.
The optical drive bays effectively block a number of the top cable routing holes.
It looks like it could be tight getting all the power and other cables through the cutouts if a decent thickness rad is used (I was going to use a SR-1). Don't like the idea of mounting the fans the other side of the 'chassis' either to fit thicker rads, meaning no dust filter.
The PSU was trickier to get in than with most cases, not helped by the position of one of the hot-swap HDD bays.
Overall it's not a bad case, but I think my expectations were unrealistic for a cheap case so ultimately I've come away feeling a bit disappointed with it.
