Have a peek at the CPU back plate cutout. The space in-between the motherboard tray and backside panel is roughly 3 CM deep, so you have enough space to work with for your cabling behind the motherboard tray. The CPU back plate cutout is there obviously for CPU coolers, if you need to swap one this helps you from having to take the motherboard out of the chassis. Right, as promised a photo of the chassis rear side with the panel removed. You can see how hard it is to photograph in a white studio with a white chassis. Cable management won't be a problem. There are many grommet holes.

Also, notice the two rectangular 'trays' ?  The two trays are intended for 2.5 inch drives, each device will be held in place by a single thumb screw. Once removed you screw the SSD to the tray and then mount it back again. These extra bays allow you to install two SSDs,  and yes we assume you won't be installing slow 2.5" laptop HDDs, eh? (Ed note: is that a robot face? with the two black screws and the wide grommet...)

You have roughly 3cm of space in-between the panel and motherboard tray, that's plenty for cable routing really.

 Installing an HDD is simple, you mount the tray clip onto the HDD (you bend and slide it on there) ...

And then you slide it into position until you hear a click. BTW these drive cages can be removed or partly removed, as part of the modular design; all three cages can be removed actually if having only two 2.5" bays behind the motherboard tray is enough for you, or if you simply need the extra space of course. 

ODD rectangular -- for optical devices it's even simpler, slide it into the 5.25" bay. And then secure it with a tension lock, simply click it backwards and it's mounted. It is that simple and works better than any other design I have seen in the past.
