I don’t want to run a server for selfhosting, so I just have my library (about 300GB of mostly OPUS files) On my pc and on a 512GB microSD card in my phone.

I use Foobar2000 on PC and Poweramp on Android.

Same thing with HP. Their “Pavillion” series of Towers contains a proprietary motherboard and power supply. Also, on the model a friend of mine had, the CPU was AMD, but the cooler scewed on top was designed for intel-purposed boards, so it looked kinda frankensteined.

So in essence, it’s the same with HP.
