I've built a few PC with the PC-Q07 (previous version of PC-Q11) are they are really nice cases. They are even nicer if you
don't get a standard PSU for them.
The CPU HSF fights with an ATX PSU in these cases for breathing room. The standard Intel HSF comes pretty close to the back of the PSU and it gets hot and noisy. I would look at getting a picoPSU for the PC-Q07/Q11. You can get a plate for mounting a 80mm fan and the picoPSU power jack in the PC-Q07. If you're not into that, this is a great PSU for the PC-Q07/Q11/Q08 cases:

PC-Q07/Q11 + picoPSU makes a great very quiet small footprint desktop PC that can take full-size components.
Here are some picture of the PC-Q07 with the picoPSU:

Here's a recent thread about running SandyBridge w/ picoPSU:
