So I have an old dell Dell Optiplex 3020 that I felt like spending a few hundred dollars on (~ 300-400). Given I have come to understand PCIe SSDs are not supported I'm opting to install a decent PCIe Wireless card. I'm looking for a decent Wireless Card that can offer enhanced security. Are there such a thing as a build in hardware firewall into a PCIe Card or something that includes VPN features and or other kind of security support?
