All you non-geek, uninitiated owners of Linksys WRT54G routers who plan to sell your devices on eBay: bother not with posting a picture; you will impress the most with a serial number.

Those of you who have no clue what I am talking about, check out the background on this useful little device, certain versions of which can be modified into powerful pieces of networking equipment. Get one for a few bucks, and let the power of Linux turn it into a a file server, VoIP adapter, firewall or a secured wireless hot spot. You can even increase the transmission power, but make sure you follow the modding instructions on adding a fan to prevent overheating.
