Product Showcase - Interior

 
On the rear left we spot another fan, obviously the rear exhaust fan which is a 140 mm fan x 1, 1200 RPM, 19 dBA. Cooler Master uses black cabling for the fans and wiring overall. 
  

 
The usual spaghetti of cables is mostly for front panel connectivity. Cable routing is just not a problem with this chassis though. Mind you that the front-panel USB 3.0 connectors must be connected to the proprietary USB 3.0 header on the motherboard. Also the LED lighting system will need wiring to the PSU of course, hence there are quite a number of cables to deal with. 

 
And all the way down, the power supply compartment (which is huge in length). As you can see, four holes with rubber inserts. Here you could mount a second SSD. It's not really what I would define as tray or would fint to be a nice location (visible), but heck OK it is a second position that is available.
