Thank you for the detailed reply. My major issue is the color difference. I deliberately didn't go for stryker as I dislike the white color. Also, I know for a fact that I will never be able to match the color of a spray painted stryker panel with a grey one that matches up with the trooper. And unfortunately, I really cannot afford to buy a brand new chassis just for the side panel. I recently had to upgrade my PSU, GPU and Hard disks and saving up for a GSync monitor. I was hoping to just buy a side panel if possible at all.
Making it myself is also not possible as I do not have dremel.
