Hardware mounting layout

I just got everything hooked up and running on Hyperion, tested out the lights and watched 20min of a movie to test, all is good. Now I’m ready to mount the pi4, capture device, and 5v power supply...just wondering if y’all could post some pics of your hardware layout behind the tv? Ok to mount psu to tv? Best to get a project box? I’m running 336 ws2812bs on a 75” tv on a wall mount with power plug there readily available for the psu. Thanks
