ive always wanted to upgrade it; but im not going to go spend 200-300 bucks buying a jacked up price cpu upgrade by price gaugers on ebay to do it. i know from experience how buggy + how much of a nightmare some cpu upgrades can be.
This is My exact feelings for mine. wasnt sure if there were cheaper alternatives to upgrade my good old Mac. but sometimes i take on challenges just for the experience of doing it.
in this case i will probably pass
would be nice to know its the same mac i had as a kid with More upgrades but i guess for things that need more power.
albeit no OS 9 i have my 15" PowerBook G4 1.5Ghz with 2GB or my iBook G3 w/32mb video @ 800Mhz with OS9 /10.4.11
looked in my area for some older G4 Towers seems there are a few spread out but they vary from $50 for models i dont want all the way up to $250 for people seeing theirs as treasure
but there is a mini G4 for $50 just unsure of specs or even if it has power cord
