THE DUKASE INTERIOR
There's not much interior space available inside the Dukase largely due to the lower area cover.
At the front we see the two 5.25" bays and the 1.44" FDD mount (the first feature tool-free brackets while the 1.44 bay can also be used with a 3.5" drive).
The mainboard tray has a total of 8 holes for cable management (unfortunately not rubber coated).
Beneath the 5.25" optical bays the area is empty not only to allow the installation of very long graphics cards (390mm in length) but also because you can mount a 120/140mm AIO solution there.
The PSU area cover has two 2.5" trays on it made out of aluminum.
All 7 PCI expansion slots are secured in place via regular thumbscrews.
Another 2.5" drive spot is placed at the rear of the mainboard tray right beneath the 1.44 FDD bay.
You can also mount two 3.5" drives on the other side of the PSU area cover.
These drive trays are also made out of aluminum.
Because of the PSU area cover things are quite strange so you can't mount anything over 170mm in length.
