THE F12C INTERIOR
Removing the top panel via the two knobs is very easy and fast.
As you can see for a desktop case the F12C has lots of available interior space not to mention two rails which can be used to mount 120/140mm fans, 2.5/3.5" drives and even a 240mm radiator.
These 8 pieces of aluminum (4 on each side) can be used to mount anything you want on the two sides from drives and fans up to radiators.
Streacom has used a unique way to keep these pieces in place and it all has to do with pieces of metal you place between them and the case itself.
Unfortunately the 7 PCI expansion slots are kept in place with regular screws.
Prior to installing your system parts i strongly recommend removing the left side panel as seen above (simplifies things) and of course the two rails.
