A:Answer curious computer guy,
If you want to connect to a WiFi network, without running a cable from the system to a WiFi router simply to have the system on the same Local Area Network, then you will have to have an adapter.
Many WiFi adapters are easily installed, without having to open the case, attaching to a USB port.
Whether installed internally or externally, however, any component that is properly installed and does not damage the system will *not* void the warranty on a CybertronPC computer, such as the Patriot.
