I thought it would be interesting to see just how far our love of these older systems have pushed us financially. In other words how much was your most expensive ppc mac or how much have you spend on upgrades to increase your performance. Currently the most expensive ppc mac I have including upgrades is my iMac g5 17 inch 1.8ghz ambient light sensor model. The machine was picked up in tandem with an emac 1.42ghz for $60 for the pair. I upped the ram to 2gb and threw in a ssd I had in my power mac g5 quad. Over $100 in upgrades but I love that machine and to me it was worth it.
