Optiplex 9020 AIO No Wifi?

Just got a 9020 for the office and was surprised to find that it doesn't have wifi. I've done some searching and haven't found anything about this on the message boards.

Is it possible for me to install an Intel 7260? It looks like the Win 7 driver is compatible. I'm thinking of picking one up and trying it since they're only about $20 on eBay.

Anyone got any experience with this?
