Andropov Posted April 1, 2012 Share Posted April 1, 2012 It isn't good hardware, but I just want to give a speed up to my old 300Mhz B&W G3 using some hardware that I have lying around. Specs: - Unknown motherboard - Intel Core 2 Quad a 2,66Ghz (Before: PowerPC G4 a 300Mhz) - Nvidia GeForce 8400GS en PCIe (Before: ATI Rage 128 en PCI) - Hard Drive IDE Western Digital 160GB (The same) - RAM 1GB DDR running at 1066Mhz (Before: 1GB PC100) - CD/DVD double layer drive (Before: lector de CD-ROM) Some photos of the original PowerMac G3 (sorry about the poor quality of the first ones): Just the original computer open. The old CD-ROM drive The old processor, a PowerPC G4 running at 300Mhz. And after the mod (in progress): I don't change anything in the external case appearance The new mobo. It's on a wood panel because the moounting points are too difernt and I would't break the entire chassis. The CPU heatsink hasn't got a fan on it because it crashes with the power supply and I can't close the case. At least, the wooden panel will eliminate all the vibrations of the graphics fan. The hard drive on its rack. It isn't connected because I need a larger molex wire. I take this photo before I put the new power supply. The new power supply. I take out the louder, bigger, 120mm fan, and I put a 80mm one, taking the air out of the case. I will cover the hole with a PVC panel. After put the new power supply. As you can see, I need a larger molex wire, a larger chipset wire and a larger CPU wire. A photo with the case closed. As you can see, the heatsink is really near to the power supply. If I put a fan over the heatsink, the case wouldn't close. So, maybe I'll use a water cooling system. After a few months I want to use a water cooling system, with a double radiator in the bottom of the fan, replacing the hard drive rack. And I change the original yellow led of the power button, now it's blue (I think it looks better). Sorry about my bad english :wink2: Link to comment Share on other sites More sharing options...
buoo Posted April 1, 2012 Share Posted April 1, 2012 You are doing a good work I have a PowerMac G5 Case too, but I have no time to keep my hands on it :\ Link to comment Share on other sites More sharing options...

Andropov Posted April 5, 2012 Author Share Posted April 5, 2012 Nice work! I've done the same with a G5 and i have a G4 in my basement too and also a bunch of hardware, i'm also planning to do that with it :wink2: You are doing a good work I have a PowerMac G5 Case too, but I have no time to keep my hands on it :\ Thanks! Finally, with a cardboard box I found a provisional solution. When I close the case, the CPU heatsink is in front of the fan. I was measuring the area for my 2x120mm radiator. In the bottom of the case, I've a 290x130mm area, completely clear from mounting points. I think I should use an Alphacool NexXxoS ST30 Full copper. It has a 15mm spacing between fans, so it's a little bit longer, perfect for my non-standar 290x130mm area. The radiator measures 279x 124x30mm. For the CPU block, I'm planning to use a EK Supreme LTX Acetal Black. But, Can I use 90º fittings for the block? The area for the radiator: Link to comment Share on other sites More sharing options...
