Hiya I am looking for a new computer to replace my aging Power Computing Macintosh clone. Yes, this machine has been through several upgrades, however, I can only upgrade it so far. It is currently running Mac OS 10.1. I need to be able to use my SCSI and standard ATA drives, which use PCI cards to access them. Having standard PCI cards is very important, as I have yet to see any PCI-X cards on the market. In addition to having PCI cards for standard ATA and SCSI (both internal and for external drives), I also have a PCI card that allows for five USB ports including one internal port (inside of the computer), as well as both firewire 400 and 800. Since the new PowerMacs do not seem to have any internal drive bays, the Zip, Jaz, PCMCIA card readers, and Tape drives mush be placed externally, however that requires having an external SCSI port, which no new Macintosh comes with, thus I have to keep the SCSI PCI card. The 1.6 GHz PowerMac G5 appears to be the only new Macintosh that will run standard PCI cards. The 1.8 and 2.0 have PCI-X expansion slots, which are incompatible with any normal PCI cards, and there does not appear to be any PCI-X cards on the market right now. If Apple cuts the PowerMac G5 1.6 tower, they will be cutting out the use of PCI cards when there are no PCI-X cards yet on the market. So, basically, the 1.6 G5 tower needs to stay, or Apple needs to find a way to use older PCI cards, or they need to come out with some PCI-X ATA and SCSI, controllers.
