At the backside you can see that the PSU is extended outside a little, this way you can fit large PSUs with a length of up-to 19 CM. Though sufficient we'd like to have seen a little more PSU space though, as a lengthy PSU also needs to deal with the wiring at the back-end.

The stands at the bottom have rubber pads to prevent resonating noises. You can see another two dust filters here, easy to take out and clean for sure.

At the backside we see that  huge mainboard tray cutout again, that's for replacing fan brackets that need to be mounted at the backside of the motherboard. Easy access. That cutout is huge alright, yet does not make the mainboard tray any less sturdy. In fact the entire Cosmos SE feels like a sturdy chunk of steel. You might be wondering where are the other two SSD mounting locations? Well, on the bottom left is where the 17th location is and the top left is the 18th. There's plenty of room for cable routing by the way. Even the rear side panel has indentations giving you a little mroe extra space for the cables.
