I'm gearing up to sell my trusty ol' G4 tower, and was wondering what you guys thought as to price points. Looking around on craigslist and ebay i've got a hazy idea of what to go for, but have yet to see anything truly comparable. Older stuff seems to be going for a fair bit, and newer stuff tends not to have aftermarket upgrades like additional HDDs, better graphics cards, other PCI doodads. the system is as follows: quicksilver G4 dual 1ghz superdrive, internal zip 250 80gb and 160gb internal hard drives ATI Radeon 9800 PRO 128mb USB 2.0 5-port PCI card (4 outside, one inside) 1.5gb RAM (maxed-out) I also run dual monitors with two CRTs that i'd basically throw in for free (19" was attacked by a cat, 15" is just not worth much). It was used as a 3D/video editing workstation. Any thoughts?
