Product Showcase - Interior
Here the PSU compartment, as you can see there's juust plenty space and clearance here; it can be up-to 200 mm in length should fit fine. Remember, the maximum motherboard size that can be used is ATX. And yes uh,... the cables colors ...
Above you can see two slots for optical, yet you can mount only one 3.5" HDD, again this is something I do not understand. Surely having more HDDs is more important than having two optical units in the year 2016 ?
When I flip the chassis around then at the backside we can mount one 2.5" SSD that we need to screw it secure. So yes, that pretty much sums up all storage options.
