about 3 1/2 long but on a PowerMac G4 they are about 5

I'm no hardware expert, but I think the short ones are 32-bit, and longer
ones are 64-bit.
Actually there are at least

PCI-X - its fully backwards compatible with regular PCI, but can operate
at 64bit and 66mhz or higher depending on chipset

There are multiple standards for the PCI spec, and some long cards. The slots
in the Mac fit both, the PC ones don't.

PCI-X - its fully backwards

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

According to this from Apple, no G4 has PCI-X:

I ran into this recently trying to get a ppc G5 MOTU audio card.
even with a long detailed conversation on teh phone with a MOTu tech
advisor, we STILL got teh wrong card shipped to me.

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

The early, low integration PCI cards needed all the space which could be
provided by the original IBM specification for the PC.
Still, even on a late Mac PPC, long cards
These are 64bit PCI slots, not PCI-X, there is a huge difference. There was
an early G5 PowerMac that had PCI-X slots but no G4 ever did.
