Why are the PCI ports on the PowerMac G4s so long? On PCs they

PCI-X - its fully backwards compatible with regular PCI, but can
operate at 64bit and 66mhz or higher depending on chipset
capabilities. More common in servers then desktop machines.
No. The long slots in a G4 are NOT PCI-X. The original PCI slot spec
allows for a long version that requires the extra slot length.
Uh, I think your confusing full length cards and regular length cards.
Both of which could be PCI or PCI-X. Card length is not the same as
slot length.
The G4 has PCI-X slots - I have a MDD sitting here, next to me, with a
PCI-X fibre channel card running in 64bit, albeit its the older PCI-X
standard so it only runs 33mhz.
Just confirmed this with Mactracker - there's 4 PCI-X 64bit/33mhz slots.
