After scouring the Internet for information on people upgrading their Minis to 802.11n wireless, I found many sites where people talk about putting the new card in but no one discussing where they put the required second antenna.

 

Despite the small size there is actually quite a bit of space inside the Mini, so here is my solution to putting a second antenna into the mini to bring it up to Airport Extreme (n) speeds.

 

Mini Intel Specs

Core 2 Duo 2.33 - 2Gb RAM

160Gb 7200 Hard Drive

Airport Extreme 802.11n
