I noticed that someone with a bunch of O2 parts seems to have finally given up and started lower the prices. I've bought a new CD driver cover (they break notoriously easily) and a long coveted 300mhz CPU upgrade. I haven't gotten around to installing them yet though. I haven't used the machine in about 12-15 years.
I probably should be keeping an eye out for maxing out my Octane and Fuel as well now before it is really too late.
