No, it will not. Unlike earlier G4s, the MDD CPUs will not work in any of the older systems.

Most other CPUs won't work in that machine, either. They switched to a 133MHz bus (that thing is 100), so those won't work, and the CPU socket in that machine is in a bad place that makes it hard to upgrade.

You might be able to squeeze a dual 450 into it... but as I recall, you'll have to desolder the CD-ROM IDE port from the board and use a PCI IDE card. And I could be entirely wrong and thinking of a newer model, too. I can't recall for sure. You'd be better off just buying a (painfully expensive) 3rd party upgrade card.

Cool, thanks. I just bought it to play around with anyway so I guess I'll just go the 3rd party route later on.

You may or may not be interested, but this is what *I'D* do with it:
  1. RAM: Max it out at 2GB with 4 of these
  2. CPU: Go dual, 1.2GHz +. This is the slowest one OWC offers now, and it's definitely the best bang-for-your-buck. You could go to dual 1.7s or 1.8s, but it wouldn't be worth the cost premium.
  3. Video: Flashed GeForce 6800- I recommend you flash it yourself rather than paying someone on ebay that likely ripped off the knowledge of how to do it from the guys that figured it out without giving them any credit for their work.
  4. Hard Drive: SATA drive, 7200rpm, 500gb+ and/or 150GB WD Raptor (10,000rpm) boot/system disc (yes, they sell smaller Raptors. AFAIK the areal density of a BIG 7.2k drive makes them on par with, or faster than, a 74GB Raptor. I suggest this Raptor or this 7200rpm drive.
  5. Hard Drive Controller: Sonnet Tempo SATA 2 port PCI card
  6. Optical Drive: This Pioneer drive *should* work. You might want to check around, but I would expect it to... Pioneer provides some of Apple's drives, and they tend to work ok with OSX. Usually. I'd double check.
  7. Audio: M-Audio Revolution 5.1 or 7.1 (even if you only have 2 speakers, these cards sound AWESOME-MILES better than the built in sound-and are OSX compatible)
  8. Peripherals: Combo USB2.0/Firewire card, such as the Sonnet Tango
  9. Power Supply: You didn't honestly expect to get away with all this on the piddly little 200-odd watt unit that's in it, did you? No, no. You'll need an upgrade. Which, ideally, means modified PC power supply (the modifications aren't difficult for use in a Sawtooth) This is a high quality unit that would require minimal (if any) modifications to the case to fit, I believe. This Enermax unit is very, very nice. It has modular cables, which is great for a tiny case like the G4's where things will get very messy, very quickly with most PC PSes. It will also greatly improve case cooling. However, if you just throw it in the case, the fan will be facing the left side panel of the case, not towards the logic board. This, obviously, negates any chances of improving the cooling and could very well lead to a well-baked PS. Which means that mounting that PS in the Mac case will require fairly simple (but time consuming) modifications to the case. Mods which will require power tools.
  10. Cooling: Apple did something that wasn't very intelligent with this machine. They used a thermally controlled cooling fan (good), but they used it as an intake fan, and the thermal probe that adjusts fan speed mounted in the fan frame near the hub. What this means to you is that the fan speed is not affected to any significant degree at all by the temperature of the computer; it responds to changes in ambient air temperature. This doesn't help you. They got away with it with the original machine because the 450 runs so cool you can use your finger as a heatsink for several minutes after its powered on (as long as it's just idling in OSX after you boot it), and the Rage 128 doesn't get much hotter. Dual 1.6s, a modern hard drive or two, a modern graphics card and 2 gigs of ram is, ah, a little bit more heat to deal with. I recommend you replace the case fan with this one, which can be set up for manual fan speed control (thus you can set it for the highest speed you can stand without tearing your hair out), or something like this, which may or may not be too loud. I don't know what your tolerance level is. Barring those choices, I'd be happiest if whatever fan was used was pushing at least 65CFM (give or take a bit) through the case though, since it IS the only fan.
  11. More Cooling: A lot of 6800s have coolers that take up the 1st pci slot below them. The ones that don't run VERY hot. I *think* this cooler will fit in the G4 case without any problems, but I'm not entirely sure. You'll also need some RAMsinks, such as those. That price is for a set of 8, I think. It's either 8 or 4, certainly not per heatsink.

So yeah... Take that for whatever you like. I haven't *tested* the system I outlined above, I don't even have my B&W G3 (which has a virtually identical case) here at home to check out some of my theories. But to the best of my knowledge, all of the above parts will physically fit in the G4 case, and they OUGHT to work just fine. If you choose to take any of those ideas to heart, I suggest you try to verify that they'll work. The only ones I have any concerns about are the video card, the optical drive, and the video card heatsinks. I'm 99.99% certain that everything else is just fine.

Wow geeky, are you maybe just a little excited over my new purchase? Thanks for all the info but I already have a pretty high end macpro so this is just gonna be a little toy to play around with. I want to spend about $400.00 on it. I really just want to get it to where I can install Leopard and maybe play World of Warcraft. You are correct about the speed of the lagrer 7200 RPM drives coming close to matching the performance of the raptor though. I have like 5 250GB Hitachi desktstar 7200RPM SATA drives just lying around that I could put in it. I was planning on getting an nvidia card to flash. I have about 10 similar cooling fans to the one you suggested, they even light up in blue. I think I may even have some PC100 ram in my junk closet at my house in Hattiesburg. Ooh I just found a 350 watt power supply in my office closet!

Welllll... more like "nothing better to do on a Thursday night" That and I figured that even if you didn't have a use for the info, someone else in the same situation might find the thread and use it.

Sounds like you're all set... Only thing to be aware of is these machines aren't like newer Macs as far as RAM goes. They're fickle. Depending on the age and size of the RAM you've got, it may or may not work. They require low density SDRAM.

Putting high density stuff (newer, cheaper) in it won't hurt it, but it will cause it to either not boot until you take it out, or just ignore the high-density stick(s).

Well I got the computer and CPU upgrade today. I ended up going with a 1.2GHZ G4 from OWC. I replaced the 20GB HDD with an old 100GB HDD i had, I added 2X 256MB RAM that I had laying around, replaced the combo drive with a super drive, and I plan on replacing the video card with a ATI Radeon 9800 I already have as soon as I can flash the BIOS. I got Leopard up and running in no time and it appears to have no stability issues. I think I came out pretty good on this. I only had to pay $200.00 for the CPU upgrade and $60.00 for the computer. Not bad for a Leopard capable Mac!
