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.

Since the 509 is large enough to accommodate an E-ATX sized mainboard our regular ATX sized one leaves a bit of room on the tray.

Here we’ve used a 60mm thick, 360mm long radiator on two of the three available mounts (you can also mount one where the drive cage is located so you can basically have up to two 360mm radiators inside the 509).

Of course you can also use the tallest and largest CPU air coolers in the market today while mounting a 2.5” drive requires the removal of the aluminum mount(s).

With enough space for up to 370mm long graphics cards you should have no problem mounting the longest one’s ever manufactured (unless if you decide to place a radiator where the drive cage is located that is).

If you choose to keep the 3.5” drive cage at the base of the case and you can’t put it on the other side because of a radiator the PSU area is enough only for roughly 180mm long models.
