Cooler Master RC-130-KKN1 Elite 130 Mini-ITX Desktop Chassis

As the title says, get a modular PSU. The case is already cramped without you having a mass of cables lying around.

I'm able to fit a corsair H80i GT cooler in this case, plenty of room in the front as long as you have the patience to mount it.

I don't know how anyone would be able to fit anything more than 4 drives in this case. I managed to get 2x SSD mounted side-by-side in the CD-ROM bay and a single 3.5inch drive mounted to the vertical mounting bracket. I'm certain I could get in another 3.5 or 2.5 if I had a modular PSU.

Somewhat poor airflow outlet for the graphics card. (nowhere for hot air to go.)
I'm unable to use anything hotter than a GTX 960 in this case as the heat slowly builds up inside the case around the graphics card.

The included side 80mm fan helps somewhat if you reverse it so that air is being blown out of the case, although this fan is incredibly noisy even at the slowest speed, a PSU with a large 12cm+ fan will help greatly.

I've modded the case to pop-rivet a handle onto the top for easier carrying.

Overall this is a great case for those looking to buy a mini-itx build on a budget, all these should be seen as minor issues, the money you save with the case should go to a modular PSU.
