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.
As you can all see using an E-ATX mainboard goes all the way down to the base of the case so you can't mount a radiator at the bottom (fans can be mounted without issue).
Here we mounted a HyperX SSD to see how it looks on the vertical tray.
You can install CPU coolers up to 160mm in height and although some may not fit the 303 was not really ment for air coolers to begin with.
There's also enough room inside the case to mount 350mm long graphics cards (if the tube reservoir area is taken the maximum length is around 275mm).
Unfortunately although the PSU area allows installation for even the longest power supply units it's also designed in such a way that the PSU sucks air from the interior of the case so if you decide to mount a 360mm radiator in front of the hexagon mesh it will suck air from that.
