Product Showcase - Interior
Here, you can see three cable cut-outs to the right of the motherboard, all fitted with rubber grommets.
However, the ones near the PSU shroud don’t have grommets in them, nor do those above the MoBo.
At the front, you can see space (already occupied) for two 200 mm fans or three 120 mm fans/two 140 mm ones.
You can install an LCS there, provided that it’s nothing larger than a 360 mm rad. There enough space even for a 70 mm thick rad, as the fans are installed on the “outside”.
At the back, there is a 120 mm fan installed. You can mount a 120/140 mm AIO in there instead.
You can install up to two 2.5” drives at the back, below the backplate cut-out on the motherboard tray.
There are also two 3.5” trays (you can use 2.5” ones instead) at the bottom, toward the front of the case. Overall, you have four drive mounts in the Helios 500G. You can also see the PSU housing here.
