WEP cracking

I've always heard that WEP keys are easy to crack, and I was wondering if it would be possible to do so using some (very) old hardware I have lying around.  Specifically, all I have available is a SMC2632W PCMCIA card, a WUSB11 linksys usb network adapter, a quite old laptop, and a decent desktop. 

When I look at the software and information I can get from google, everything seems simple except capturing the traffic to analyze.  Are there any utilites (windows drivers or a linux build) compatible with my wireless card, or is it impossible?

Any help will be appreciated, thanks. 

1. Go to bestbuy
2. Purchase wireless card that only current function isn't building material in africa.
3. ???
4. Profit

Or if you prefer not to leave the house,
find/replace bestbuy with newegg.
