Just a heads up to open the SS1 and inspect fasteners
I opened my SS1 to install a 40mm Noctua fan (45mm hole layout but I made it work.. odd size??).
I found one loose silver mb screw bouncing around, and one of the heat sink fasteners had come loose, causing the heat sink to tilt up at a 30ish degree angle.
Easy fixes, but I wanted to drop this as a heads up for anyone who hasn't opened their SS1. It's worth checking to see if anything came loose in shipping or was overlooked during manufacturing.
On a positive note, the board layout is beautiful and I've had zero performance issues. I have an OG PS1 but the SS1 has become my preferred way to play. Totally converted me.
