I had considered the idea of a SATA card or SATA drive via Firewire, however it still leaves me with a basically maxed out system in every other respect... the RAM ceiling of the Yikes is 1Gb which Ive reached already, and the CPU speed is as far as it can be stretched too... the logic board on Yosemite/Yikes basically only allows for a CPU clock multiplier of 5x the bus speed meaning 500mhz which its also runniing at now. I believe one can hack the bus speed from memory but its not guaranteed to work stabley or reliably. It's been fun seeing my Yikes progress into this monster over the years, but I do think its time I finally put it to the side and started a new PPC build-up. I'm looking at a dual 1.25 FW800 MDD at the moment with studio display to match for about 50 bucks so I'm thinking thats gonna be the new toy.
