I bought this specific case to build a NAS for personal use and it was exactly what I expected. It is small and obviously if someone wants to install 6 drives like me, they will have to do very careful cable management. The drive modules are easily removable and installable, and the drives have enough distance between them so that air can flow easily and they don't overheat.
If someone wants it for a regular PC, I think they will struggle with the space for the graphics card and cables.
It would be good for anyone interested to have a modular/semi-modular PSU.

Initially, I had given a quite negative rating due to the limited available space, stating that it barely fits one HDD and one SSD. However, last week I installed a new power supply (be quiet! P9 600W) and a graphics card (XFX R9 270X) and they fit perfectly. I have never installed such hardware before (the most I had done was to install an HDD), and as a beginner, I managed it extremely well. It should be noted that the power supply is fully wired and the graphics card is quite large in size, which made cable management a bit challenging, but I am sure that in the hands of a more experienced person, it would be very easy. Despite my belief that the PC would generate high temperatures, the CPU has a maximum temperature of 65° (average 50°-55°) and the graphics card has a maximum temperature of 60° (average 45°-50°) with prolonged use in games like CS:GO and Fallout 4.

Obviously, as an ITX case that can fit 6 drives while remaining small in size, it couldn't offer both space and easy cable management. So, there are definitely some compromises that are normal for such a case.

Positives:
- Very good airflow for the drives and its size, with quiet fans.
- Very stylish and simple, easily fits in a living room.
- One of the few cases under 200€ that can fit 6 drives.
- Can accommodate a tower cooler up to 160mm!
- Can fit a fairly large graphics card if combined with a short power supply.

Negatives:
- Build quality, 1mm sheet metal, the thumbscrews were probably screwed with a pneumatic gun and had cut some tabs from the pressure.
- Price, for the above build quality, the price is the same as an FD Define S or Corsair 400q.
- It has no sound insulation and doesn't have much space either.
- Difficult closing of the lid
