Had issues with the Layout and running temperature of my previous LianLi ITX case, especially as my new graphics card only just fitted in the case if I removed the front USB ports.
AS Rock Z77e-ITX
Intel i5 - standard heatsink,
Radeon 6770 Graphics card,
CIT ATX PSU.
Found the Qubz layout to be a lot better, with more space around components. I found that my graphics card temperature had dropped 15 degrees by changing to this case.
Install was pretty straight forward, the only thing I would advise is if you are using a full size ATX power supply to fit it before you fit the motherboard. Also fit the DVD drive after you have mounted your hard drives.
Would definately buy another.
