last one. I know should've provided the link... but just thought about it. Follow the link on the pictures. Anyway...
how did you get a hold of one and did it come with a regular keyboard from the emac? got any photo's of a 1.6???
Stole one from the display at WWDC. Straight GANGSTA!!! Just took it. Put on an apple employee uniform and walked right out.
Re: 9 fans...
The Cube was fanless. The Bondi and Rainbow iMacs had a fan (233, 266, and 333 MHz) but the Kihei iMacs after that (all other G3s) were fanless.
One thing I remember from taking PC Repair my junior year of high school is that at least with a PC motherboard, you don't actually clock the processor, you clock the bus speed and the multiplier. With the G5, the multiplier is probably stuck at 2x. So you couldn't upgrade the processor without overclocking the bus to the failure point.

The original iMac was fanless. Wasn't the Cube as well?

Re: Re: Re: Possible solution for upgrades
You are definitely correct regarding the PCI-X that's currently used in the G5's. However, it seems that the newest PCI-X (revision 2.0) is indeed faster than AGP 8x. It goes up to 4.3GB/s.
hvfsl's speculation that the next PowerMac G5 revision might eliminate AGP 8x in place of PCI-X is still possible.

Correct me if I'm wrong but I vaguely remember Steve Jobs (during the keynote) saying that the fans were controlled by firmware. Am I remembering correctly? If that's the case, maybe the upgrade makers can get away with a firmware patch.
powermacs cpu and video upgrades
the words powermac and upgradeable cpu and video upgrades go together even apple made a few.
7300-9300 g3,g4s.
this is what made then pro machines while imacs emacs and such are consumer machine.
i upgraded my bw g3 300 to a 550 oc @600 g4 and it made a world of diff esp in osx took out the cdrom put in a combo drive. and with the exception of video (agp ) it benches as faster the last years 800 emac/imac (were $999+back then)
for 250+89. the smaller pipe 4stages and larger 1MB L2 cache really helped for 1/3 the price of new.
i think apple is simply warning the upgrade companies to make sure they address the cooling problem as apple will not be liable for problems cost by them.
there is no way apple can sell a $3000 desktop that can not be upgraded by cpu. if so the pc's can used this in there advertisement.
all they need is to add new fans and sensors for additional cost.
i hope to have my G5 by march and to upgrade it in 2 years or whenever the speed doubles and to get a new mac evety 4 years but i am keeping my bw workhorse.
if you absolutely cant upgrade the cpu then maybe ill just get a left over g4 cheap since i really dont need the speed but it would be nice.

Finder
I say the new Panther finder looks more start menu-ish than than the Jaguar finder. Apple copied the star menu. Kind of.

Re: Finder
No, they copied the iTunes playlist list and the iPhoto album list
Apple hasn't made processor upgrades until 1994, 1995 or so. And there was no Power Mac 9300.

Re: Re: Re: G5 FSB
It's an important distinction when it comes to processor upgrades. At any case, the mobo is likely stuck at a the 4x multiplier.

Re: Thermal is probably not the issue
I predict that when the G5 hits stores and lusers start buying them left and right, this pairing RAM sticks thing is going to be lost on most people, and since most people buy aftermarket memory and upgrade themselves, they are not going to be running in an optimal configuration.
If you don't pair your DIMMs properly, your computer is crippled and only operating half as fast as it should on some tasks.
Dude, why didn't you just buy 2x 512MB DDR400 sticks? It would have been cheaper and you get to take advantage of your full 800 mhz. FSB right now...

The Apple Store only sells RAM in properly paired configurations
