Looks great, but terrible cable management. Its a two man job to get the back panel on...

Clear panels are good but only has 3 fan slots

Great Case! Looks beautiful. NOT tempered glass but gives the impression which is amazing. Not a lot of room for cable management, and only has 1 SSD mount. Front panel comes off very easily and the power button feels good.

I like this case, the aesthetics, the compact form. It's not a 5-star case cause the average cable management. The plastics are good, but the metal cage feel cheap, it flex easly when you mount the front fans. There are rubbered feets for PSU. For a 40$ is good case.

It looks really neat, can't say much because I have been using a laptop for 6 years

Great case for the price.

Also comes with customizable trim colors - red, black, and white which you can swap out any time.

The Plexiglas extrusion at the front of the case comes out to mount either 2 120mm fans

Drive Bays: Only room for 2, 3.5" HDD's and 1, 2.5" SSD.

Cable routing: Very little room for cable management in my experience. Only available from behind the motherboard tray.

Dust filters on the front and bottom.

Pre-installed with one black fan (3-pin, 120mm) in the back. The front allows 2 more 120mm fans which I used.

The case supports only Micro-ATX and Mini-ITX boards.

In the future, I would get a case with more cable-management capabilities and more room for storage drives.
