Here we can see all the HDD storage unit bays a little better from the front-facing side. You'll get to mount two HDDs, that's all though. Hey, an 8TB HDD is ~200 EURO these days, combine it with a fast SSD and the sky is the limit right? Storage sweetness my man.
 

So much for the dedicated toll-free 2.5” and 3.5” drive sleds. Just one last photo showing the grommet holes with rubber inlays. It's a sturdy build alright. BTW look at that huge air intake at the front side(s).
 

As stated, the PSU space is a little limited, especially with cables coming out. At the bottom and rear side, you can remove three thumbscrews allowing you to move the unit an extra 2 cm to the right. Alternatively, if you do not use HDDs anymore, you can just take it out completely. 

As you can see, here I moved the HDD cage 2cm to the right. That brings in a bit more clearance, it is, however, a bit of a challenge to hide your residual PSU cables.  Ergo, I would have preferred some sort of cover extending over the PSU and HDD bay, or a separated compartment.
