BUILDING THE SYSTEM
As always the purpose of this section is not to build a functional system but rather to showcase what you can expect from the case at hand in terms of interior space.
Using a regular sized ATX mainboard leaves a large part of the interior empty.
Most users will probably choose the Primera PM01 for its water cooling capabilities and this is where things get a bit strange since although at the front you can mount 240/280mm radiators with ease you can't do the same with a 360mm one since it will not be able to pass through the small hatch of the PSU cover. For example we used the AX360 radiator by XSPC both at the front and top and although just 40mm thick it just wouldn't fit at the front (no problems at the top as long as you remember to mount the fans on the exterior - we also tried mounting the EK XLC Predator 280 AIO model by EKWB without luck however because of its thickness).
Being able to use 180mm tall CPU coolers means you can mount pretty much any model in the market today (if you choose not to go with water cooling).
Having a clearance of 419mm for a graphics card also means you have nothing to worry about even with the longest one out there.
Same thing at the rear since you can use power supply units up to 240mm in length.
