mike,
there seems to be some confusion so let me clarify:

a mac with an intel chip in is a PC right?
hmm, depends on definition i guess.. personally i'd call it an intel mac, but the hardware in it is nearly identical.

So once all the glossy marketing bullshit from apple has been removed, we are left with a piece of good news. It is now possible to buy a version of OsX which wil install on a PC.
if you mean "buy a version of OSX for a non-apple computer", nope, you can't buy that. you could hack it, but you'd break the software agreement of OSX (and quite possibly of shake).
it is, however, leagal to install windows on the mactintosh machines (although it's not trivial because it uses a different boot system). for most purposes it will also be possible to "emulate" windows in a layered mode under OSX with near 100% efficiency too.

I wonder if it will support AMD too?
it won't. not legally. not by apple. i guess someone will try to hack that too, but it wont be trivial. apple certainly has a door open to switch to AMD in the future, but for now i guess intel got an exclusive deal, while apple gets some advantages out of that too.

I can build a quad Opertron, put a good cheap Quadro card in it, SCSI320 RAID and 4 15k disks. I wonder how the price compares to a quad G4 with an Xraid?
why not put a SCSI320 RAID on the G5? (although personally i'd go for a SATA raid anyway, put some raptors in it if you really need the short access time). and does the graphics card make a big difference for rendering speeds? (i could imagine it will in the future, with Motion's technology hooking into shake.. but then again the linux version wouldnt get that.)
personally think about apple not as a company who makes pretty hardware, but a company that makes decent hardware with a free awesome operating system and some really good software. since they dont make much money on software anyway, their only choice is to make the hardware a bit more expensive to support all the software development. i can see this sucks for render farms though (but again, you get the OS for free, and you get the shake render nodes for free, so why complain).
as you can probably tell, i'm a mac head myself, so feel free to take the above with a grain of salt.
