One of the great Youtube links for Power Mac machines lately comes via ItsMyNaturalColor, a guy with a ton of enthusiasm and love for old Macs. He has a series about putting together the fastest Blue & White G3 tower ever, including an upgraded CPU, SSD drives, RAID drives, ATI 9200 Radeon Card, and Bluetooth. It’s a monster machine, and even if you think it is a waste of time, his enthusiasm will get you in the end.
While that is Video 5 of the series, start from the beginning if you want. It’s a fun waste of an afternoon.
As a followup, I enjoyed this video as he unboxes a G5 quad and then absolutely gets devastated when he sees what a mess it is in.
