Can someone explain to me where the 4 drives could be put in?

You have the choice of how the four drive bays are to be used: For two 2.5-inch drives and two 3.5-inch drives. Simply a clean affair - especially thanks to the magnetic dust filters!

Answer

I just installed an SSD yesterday.
At the top right it has 2 slots that can be accessed from the front. It has "little drawers" which can be pushed shut on the sides.
However, the easiest way is to loosen the opaque back plate with the two finger screws (above), fumble out the cables next to the powersupply (for the SSDs) and then put the SSDs into the slots from behind. My SSDs are too small to screw into the drawers, so I tied them with zipties... But they can also be screwed into the drawers.
