Product Showcase - Interior, the backside
You can see the big compartment here. At the bottom, there's a cage for two 3.5"/2.5" drives. You can also see the plastic cover, in the default state it covers the USB, HD-Audio cables, etc. You'll need to remove it if you want to install the Connect PSU module.
There are three 2.5" brackets in the upper-left area.
The PSU bay can house a power supply of even 280 mm in length (but usually they're not longer than 180 mm).
The 3.5"/2.5" cage is held in place by a single thumbscrew, so it's very easy to remove it.
As for the cable management, there's between 17 and 28 mm of clearance. Let's proceed to the building part of the review.
