First thing to come off is the roof. Here you can see the large LED fan - coloured blue when illuminated. It's not speed controlled and simply runs off a molex connection.
The 230mm LED fan.
The motherboard tray and backplate come off as one - this makes it easy to fully install the motherboard, chip, cooler, memory and ancillary cards. You can also see the dual 60mm fans. Just as with the roof fan these are molex driven.
Removable motherboard tray.
The PSU cradle is removable allowing the power supply to be installed easily in either orientation - you could have it the right way up or upside down.
The forward cage hold the all important 5.25" drives a single 3.5" drive and can even accommodate two 2.5" drives meaning SSD raid is a real possibility.
Front optical cage.
The last removable internal part is the 3.5" HDD cage. This can hold two full sized HDD's and even uses rubber mounts to help isolation that should reduce noise whilst running mechanical drives.
As you can see once empty there's a good deal of available space plus that 92mm fan that helps cool the 3.5" drive cage!
The empty case.
It's another blue LED model to match the 230mm fan above.
Front 92mm LED fan.
