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.
Even after installing a regular sized ATX mainboard there's quite a bit of empty space left in the PANZER-G.
As stated earlier you can mount up to 360mm radiators at the front with any thickness you want (however over 30mm thick and you will not be able to use the bottom 120mm intake fan mount).
You can also mount a 360mm radiator at the top (we didn't have two so we mounted a 240mm one) and since the fans are mounted on the outside you can use even 40mm thick models.
Mounting even a long graphics card like our GTX 590 (286mm long) still leaves plenty of room for extra fans in push and pull for the front radiator (you can even mount a tube reservoir between the card and the radiator).
Remember that to install the PSU you first need to mount the bracket and then push it inside the case from the rear.
