To the lower left we see the PSU mounting area, you can use ATX PSUs up to 180 mm deep when using the bottom fan location; when not using this fan location longer PSUs (up to 300 mm deep) can be used. I have yet to find a PSU that long though?

As stated before, the chassis comes with a good seven expansion slots. CPU coolers may be up to 180 mm tall and graphics cards up to 40cm in length. Here's the backside btw. If you look to the left you can see three removable plates, these are HDD/SSD trays, you get to install three of them with to the right another two SSD mounting trays.
 

You remove the tray with a thumbscrew, then seat the HDD/SSD on there and secure it with four supplied screws. You'll spot thick rubber grommets on all holes on these trays to prevent resonating noises from the HDD. BTW - please don't mind the old IDE based HDD, it's just a mock-up unit :)
 

So the three 3.5" HDD brackets can also hold a 2.5" SSD, at the bottom side that you'll need to secure it with four mounting screws. It's a very simple solution really, but there's nothing wrong with simplicity as long as it's functional and effective. And it certainly works just fine.

Slightly to the right and right behind the motherboard-tray there are two extra 2.5" storage unit trays. Same mounting methodology applies here. So in total you could house five storage units. While five units is not a lot, most people these days have one SSD and one or two big HDDs, so for them it'll be plenty.  The nice thing though is that the storage units are not in sight of the side-panel window, bringing improved aesthetics to the chassis.
