It's somewhat more complicated with optical drives. The problem with the plastic faceplate of the top 5.25" bay has not been solved:

It is still blocked by the top hinge clamp of the front panel and you have to unfasten the clamp to remove the faceplate. There are no problems with the installation of the drive proper. It is just inserted into the bay and fixed with a side lock.

You do the same for every other 5.25" device you've got.

When done, close the front panel:

But the front door cannot be closed now. Even though the controls of the Scythe KamaMeter are small, they get in the way. This is something the developer should have seen to. You can't install a simple rheobus into this system case.

The assembled system looks rather neat:

Thanks to the large interior, I had no problems laying the cables out.

Before testing the system case, I want to show you its specification
