Not my video but certainly one that might be of interest to the forum. The YouTuber's 6300CD doesn't have an Ethernet port* (or USB for that matter) so he devised a workaround involving an Airport Extreme which enables the 6300CD to connect to his DSL at 33.6.

You might also enjoy seeing his other PPC Macs in the video which includes a Clamshell iBook G3 that's apparently still functioning on the original 22 year old battery - an impressive state of affairs in my humble opinion.
