Not to worry, it seems there's even something better available: The Lian-Li PC-Q08B. This case is even better in all regards:
- even smaller: (W) 227mm x (H) 272mm x (D) 345mm VS 330x265x430mm
- lighter: 2.7kg VS 4.1kg
- easier to install (all 6 drives are easier to access)
- more silent because of better airflow
- does allow optical drive which the fractal design does not
- cheaper! €100 VS €150

The only thing 'worse' about the Lian Li is that it comes without a PSU. Which I don't mind because I've got enough of those lying around here and I like to choose my own PSU anyway. This is going to be the one for me!
