To get inside the case all you have to do is remove the 2 thumbscrews on the back of the case and slide the entire top off the chassis. Bgears uses a 1-piece panel for the top and sides of the case. On cube cases I am really not a fan of this design because it makes it really hard to get it back on after hardware installation. Also I noticed this panel was a bit flimsy.
Having a look inside we can see that the motherboard tray has the standoffs already installed, which is nice. This case gives you room for 4 PCI cards. Towards the front of the case you have all of your wire connections and a stop for a 80mm intake fan, although the fan is not included.
There a 2 5.25-inch external bays so you can install up to 2 optical drives. Below them is the 3.5-inch slot where the removable enclosure is already installed. If you do not wish to use the removable enclosure and want to install another 3.5-inch device or a floppy drive you can easily remove the enclosure mounting. On the opposite side of the case you will find the hard drive cage, which is removable. You can install 2 drives here.
This case also has room for a normal sized ATX power supply, which is nice so you can choose which power supply you want with this case. The 120mm exhaust fan is a blue LED fan so it will light up everything inside nicely. Also included with the case is a bag of screws, power adapter, USB cable, and instructions.
