[Paul] spent his summer bringing an iMac G3 into this decade. There’s plenty of room to work with since he removed the CRT which originally occupied most of the computer’s space. The final project is much more powerful and since he preserved most of the metal mounting parts inside it remains quite strong.
He started by swapping flat screen monitors with his Grandma (who incidentally runs Linux… nice!). She had a 15″ model which would fit nicely in the case so he upgraded her to 17″ and took the old one. With bezel removed it fits perfectly where to old tube had been. Next comes the power supply. It’s mounted on the bracket which held the back of the tube, with a bit of metal removed to clear the air intake. To mount the motherboard he fabricated a bracket at one end where the iMac’s stage drops away. In retrospect he wishes he had rotated the board to make the I/O panel more accessible. The hard drive mounts on the original carriage, and he did some creative gluing to make his replacement DVD drive align with the original optical drive opening. The finished product looks great from the front and sides, with the cables running out the back as the only indication that it’s had some major work done on it.
The hard drive in [Jason’s] 24″ iMac was on the blink. He decided that instead of just swapping out the bad drive for a traditional unit he would upgrade to a solid state drive. Tearing apart high-end hardware like this can be a bit nerve-racking but luckily the drive is mounted right behind the screen so he didn’t have to take everything apart.
The SSD he picked up was 2.5″ but the mounting hardware in the iMac is only setup for 3.5″ form factors. We would have used a bit of hackery to make it work but [Jason] went with an adapter kit. Uh-oh, once installed there was no problem with the mounting but the SATA cable didn’t reach far enough to plug it in. The cable snaked around under the motherboard and would have been a lot of work to swap for a longer one. He ended up removing all of the mounting screws except for one coercing the drive close enough for the connection.
It worked for him and it can for you as well. If you do this make sure to devise your own mounting scheme so that you don’t hit the same snag.

Saying that [Ian] had some overheating issues with his iMac G5 would be an understatement. After losing three hard drives due to heat he decided to do something about it. The first step was replacing the thermal paste with Arctic Silver. The solution for the hard drive was a little more unorthodox.
[Ian] picked up a 320GB Western Digital Caviar Blue drive because of its very low noise rating. He used rubber grommets to mount it outside the case and ran SATA data and power extension cables through a quarter inch hole to the motherboard. He mentioned to us that the cutout seen above the drive is from a previous mod.
This certainly will fix an overheating problem but it doesn’t do much for the sexy style we’re accustomed to with Apple hardware.
[Logicdustbin] sent in his iCast project. He gutted a blue iMac and inserted a DreamCast and an LCD. It looks very nice. His ports on the front seem almost factory installed. You can follow his build on the cgcc forums.
File this one under: “Wow, that’s even possible?” xbox-scene hacker [RDC] has been hard at work converting his Xbox 360 to slot loading. To start, He removed the slot loading drive from a blueberry iMac G3. The loading mechanism is the top half of the drive. He split this off and married it to the reading mechanism in the Xbox’s Hitachi drive. The difficult part came with getting the drive to properly signal when it had a disc. He put together a custom circuit to do the detection and has a thorough description of how he solved the problem.
