I have an HP desktop with Wifi. The support is via a second little circuit board that is mounted against the back wall just above the case fan, not on the motherboard. There's coax cable to a connector on the back panel and an external magnetic mount wifi antenna I could set on top or anywhere nearby. Not wanting wifi support on my desktop, I turned it off in the BIOS and disconnected the little board and removed the antenna.

OK, that's more than you asked. Yes, it means it supports wifi, just like nearly all laptops.
