So my cube has become my main machine by now. There is still room for improvement but I'm quite happy already.
I thought i'd post a couple more pictures.
After almost finishing the project I have to say that my respect for anyone who succeeded in building a hackintosh cube grew by every hour I spent. So many times I had to disassemble, rearrange, buy further parts. My skills at modding are very moderate indeed and I didn't have a lot of tools. I did one cut of the bottom plate with a borrowed dremel 300. The rest was done bey drilling and lots and lots of filing
I the and I have a working computer in the cube case with the zotac z77 itx motherboard, intel i7 3770T, 16gb ram, 256 msata corsair m4 hdd, and sony blu ray slimline burner. I exchanged the wifi mini pci card for a atheros combo card (bluetooth is still not working, so I'm using extra dongle for that).
Since wifi reception was terrible and I also didn't like the external antennas at the bottom I built in internal wifi antennas from a very old acer laptop.
So...a couple pictures:
For the bluray drive I cut the cover of the original drive as show, so I could mount the new drive.
In the middle: The basic hardware setup, GPU still with the original cooler.
On the right: The 7750 low profile with arctic accelero L2 plus cooler (fan removed); the graphics card is positioned. My first plan to have the cooler pointing to the center of the cube didn't work, the pci extension would have been too long.
I fittet two 40mm tiny noctua fans to the cooler that blow air from bottom to the top.
