The quickest and easiest way to convert that eMachines desktop to a wireless connection is to purchase and use an external USB wireless adapter.
This is one that I use and recommend:
Premiertek Powerlink PL-U3005N 802.11b/g/n Wireless USB Adapter w/Antenna
Here are some sites where you can purchase it:
