Very generous of you Titan
eRyan, I wouldn't spend more than $150 on a beige G3, especially when they're only worth ~ $100 in stock configuration.
- First up, with Titan's RAM going, I'd get another 128MB stick and try to get 320 - 384MB for OS X 10.3. The G3 has 3 x SDRAM slots, beware if you buy 256MB sticks - they must be double-sided. Note that a beige G3 isn't officially supported under OS X, and you will need to use
XPostFacto to get it to work. Bit fiddly but after that all should be fine.
- Hard disk: Pick up a new 40GB 7200 drive from any computer store for $65 - 70.
- Video card - the onboard ATI Rage graphics have only 2MB onboard, so I'd look into upgrading your VRAM to the full amount to 6MB - a 4MB module can be picked up on eBay for ~ $20. Otherwise, if you require better graphics, pick up a PC Radeon 7000 PCI card for $60 and flash it to Mac.
- Lastly,
OVERCLOCK that G3! If it's a 233Mhz chip, you'll likely get 266, same for 266 --> 300etc. You can also increase the bus speed of the motherboard to 75 or 83Mhz, experiment with this too as a higher bus = better throughput of memory/disk/video buses.
A few simple changes can make the beige G3 into a usable OS X 10.3 machine; just don't spend too much as you'll never get your investment back!
