Well. I decided after having done a few systems in the past my next project would be an upgraded G4. Heres what I started with: G4 400 AGP Sawtooth 256MB RAM 16MB Rage Pro Video Card 8x Sony CDRW Drive Ultra SCSI Card w/ IBM 10k RPM Ultra SCSI Drive It ran Tiger reasonably well believe it or not, but I needed more. Here's what it is now: G4 1.8 AGP Sawtooth 896MB RAM 128MB Radeon 9800 Pro 16x Dual Layer NEC Superdrive Seagate 120GB 7200 RPM 8MB Cache Hard Drive Airport Card WOW. I just got done testing some Quicktime HD feeds, Halo... yeah yeah but we all know what a bloated power hungry port this was, Photoshop, and a few others. Holy cow. For anyone thinking about upgrading that old G4 they have, instead of dishing out much bucks for a brand new system, jump right in. Slower bus speed, yes, but you know what? You have all of that expandability. BTW, all of this runs fine on the FACTORY 237W power supply and it's not even warm after a few hours of hard use. Next upgrade is to 2GB RAM, then we can really have some fun. Just thought I would share with everyone. Again, lot's are saving up for some new new new system when in fact they could do something like this and be amazed.
