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.
Without removing the drive cage, you still have room for PSU's up to 1KW in output.
Since the Cronus ARGB is compatible with up to E-ATX sized mainboards there's plenty of room inside after mounting our own.
According to ThunderX3 you can mount 240mm radiators at the front (30mm in thickness) but according to my measurements you should be able to mount an 360mm one as well. Also, at the top you can mount either an 240mm or an 280mm radiator without obvious clearance issues (if the radiator is up to 30mm in thickness as well).
With enough room for up to 180mm tall CPU coolers you should be able to use most models currently in the market.
Even if you do place a radiator at the front (as in the picture) there should still be more than enough room for 350mm long graphics cards.
