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.
Our regular ATX sized mainboard leaves plenty of room inside the Level 20 GT RGB Plus as you can see from the above picture (still it’s almost as large as an E-ATX model so there’s almost no room left at the lower end).
Thanks to the offsets at the top you can mount even 60mm thick 240/280/360mm radiators (as long as your memory modules are not as tall as the T10 ones we are using here).
As mentioned already in this review you can mount up to 40mm thick 240/280/360/420mm radiators at the front without removing the drive cages.
Of course with enough room for up to 200mm tall CPU air coolers you can fit any model in the Level 20 GT RGB Plus.
Mounting a large graphics card like our GTX 590 (286mm long) still leaves plenty of room until the drive cages (or the radiator, whichever you decide to place there).
Whichever PSU you decide to mount in the Level 20 GT RGB Plus there should be plenty of space for a bottom fan (120/140mm) and/or the tube reservoir bracket (that is without removing the drive cages).
Unlike other towers the PSU cover in the Level 20 GT RGB Plus doesn’t separate the interior into two sections (thus partially keeping heat from the PSU away from the rest of the case - dual chamber design) so its sole purpose is to cover all the power cables.
