Small screen inside PC for monitoring, akin to AIO screens.

When shopping for AIOs I came across a lot that have a screen on the pump head that shows CPU utilization and other stats and connects to a USB header on the mobo. I'd like sich a screen in my PC but not in the AIO, can be a segment display for all I care it just needs to show a few utilization stats. I also want it to specifically connect inside of the case and not use HDMI or something. I don't mind doing a little bit of DIY, does anyone know if there's any products offering this or any way to DIY this with a cheap screen from Amazon?
