There isn't much choice in the range of PCI wireless cards for a desktop PC, since most desktops are wired to the router so the biggest demand is for wireless devices suitable for a laptop. Since it's only going to be temporary you might want to look at getting a USB wireless adaptor which plugs into any spare USB port on your desktop PC -- those from NetGear are very reliable and Belkin make them too but the NetGear ones have more user-friendly setup software in my opinion. Going the USB route means it can be installed in seconds, and can easily be transferred to another PC if required without having to go inside the system case. They usually come with an extension cradle allowing you to place the adaptor in the best position, so you won't need to have it sticking out of your PC like a sore thumb and where it may not get the best signal strength.
