I've finally managed to get my hands on one of the very rare SONNET CPU upgrades for the PowerMac G4 Mirror Doors: (I purchased this one from a seller in Japan)

This is what the machine originally looked like on the inside: (It was originally a single 1.25GHz Machine with Radeon 9000 Graphics)

This is what it looks like now: (It's now a dual 1.83GHz machine with a Radeon 9800 Pro Mac Edition and a Belkin 5-port USB 2 PCI card, giving it four external USB 2 ports.)

The Blender Test Result for this one are out:

Here's where it fits in with the other G4's I've tested: (I still have to test my MDD Dual 1.42GHz machine at some point!)

Here's where it fits in with all of the other systems I've tested:

Not too shabby! (It's performance is pretty much exactly where it's supposed to be.)

I’ve added an extra fan which blows directly onto the CPU module:

I ran a Blender test to stress the CPU with Temperature Monitor running, and the highest temperature it reached was: 63'8 Degrees C (The current ambient temperature's in the region of 32 to 33 degrees C.)

It just beat it's last Blender score, as it did it in 1 Minute and 41 seconds!

I'm not quite finished with this system yet, as I still need to upgrade the drives to SATA SSD's (IDE to SATA converters), give it its full complement of DDR 333 RAM (2GB), install an Air Port wireless card which is compatible with modern WI-FI routers and install a 3-port FireWire 800 PCI card.
