you can buy ATA Hi-Cap driver and then it takes the limit out. http://www.speedtools.com/ATA6.shtml Just installed a 300 gig on my QS 00 OtherWorldComputing (macsales.com) sells it cheaper than oem if you buy the drive from them. Read the instructions/warnings very carefully though. no problems at all, they do recommend partitioning it in case you have problems but i have other drives to boot from.
