I have an original Polycade and I need to upgrade the network card in order to work with my new Wifi set up. I'm in the process of upgrading to Windows 10 but I'm not sure how to install the new PCIe card. I'm not a windows users so I'm a bit out of my element and I don't see a simple way to access the card slots. Any suggestions? Thanks!
Glad we were able to sort this out Tony!
For the next person: in most cases the GPU (graphics card) covers the PCIex slot. If you need to use this slot, you'll need to remove the graphics card and install an extender like this for the PCI slot underneath. Then re-insert the graphics card and you should be good to go!
