Newegg has the Rosewill RNX-N150PCx 802.11b/g/n PCI 2.2 Wireless Adapter for $12 with free shipping. If you're completely out of USB ports or if you just don't want to use one, this should stand in just fine.
^ I'd think a USB wifi adapter on an extension cable mounted out the window or on the roof would be better, if not a router-turned-client-adapter on ethernet cable for longer distance to the host system.
These work good when your are "Borrowing" someone elses wireless connection.

only 150mbps.....booooo....won't do 1080P or even 720P for that matter.
Even 300Mb leaves a bit to be desired for seamless 1080p... mere 100Mb ethernet is often better, especially if wifi encryption is used.
