This is a lot of my similar setup in hardware. I just repurposed a PC I was using for windows that I barely used anyways. I would like to move that to a Framework Desktop mounted in my mini rack at some point though.

I ended up making my own dashboard app, not as detailed as Scrutiny because I just wanted a central place that linked to all my internal apps so I didn't have to remember them all and have a simple status check. I made my own in Go though because main ones I found were NodeJS and were huge resource hogs.
