There are surprisingly no sharp edges for a case this cheap. For the first time in a very long time I did not leave my blood DNA while working on a computer case (Surprising for a $110 case).
There are two strut bars at the top of the case. To provide some integrity to the structure, while also doubling as mounts for your 3.5 inch HDDs.
Simplistic and minimalist, there are only two headers (POWER and SWITCH) plus the USB 3.0 header if your motherboard has it. A USB 3.0 to 2.0 adaptor is not included so you need to purchase one on your own if you want to use the USB ports on the side. I disabled all on board USB on my motherboard so this is not an issue to me.
There are two spaces to mount 2.5 inch SSDs at the bottom of the case. As this sits under the motherboard it’s probably best to mount the SSDs first before you fit the motherboard. Having said that, it may still be possible to angle in the SSD from the bottom with the motherboard fitted.
I am running my OS on a CFast card so I did not really test this.
