I have 2x PCIe X16 and 1x PCIe 1x slots that are not being used. Given that Linux has extensive hardware support, there are probably users with interesting PCI card usages
Aside from traditional usages like network/wireless/bluetooth/sound that can easily be used as USB (or built in advanced sound support in the MOBO), what are your use cases with PCIe?
I got a card for an extra m.2 drive, and another one with four usb3.1 ports on a separate controller, although i dont use it anymore as much. Haven’t had anything else installed in a while. The last one before that was an audio card I’ve bought around 2010, and it was a huge waste of money
