THE H600X SYNC INTERIOR
In terms of interior space, the H600X Sync seems to be doing very well (the luck of rubber grommets however stands out).
Past the front fans you can mount either an 240mm (no thickness limitation - depends on the graphics card you plan on installing however) or an 360mm radiator (up to 30mm in thickness by repositioning the bottom drive cage - no limit by removing it entirely).
The PSU cover ensures that hot air coming from the PSU doesn't enter the top half of the case and that cables are not visible from the outside (or at least that's the entire concept behind the dual chamber design).
As mentioned earlier the lack of rubber grommets on the mainboard tray stands out.
ABKONCORE has placed one of their latest HR120 ARGB fans at the rear of the case.
Turning the H600X Sync around we see two 2.5" vertical drive trays, bottom drive cage with two 2.5/3.5" drive trays, PSU area and the fan ARGB controller.
Even though the vertical drive trays are made out of aluminum the ones in the cage are made out of plastic.
You can remove the drive cage all together in order to install the thickest radiator possible (along with the longest PSU possible) or position it slightly to the right in which case you can fit radiators up to 30mm in thickness and PSU's up to 180mm in length.
