I opened my new (to me) G4 tower today for the first time thinking I'd quickly upgrade the CD to a burner and add some memory I have laying around. No problem on the memory, just added an additional DIMM to the open 4th slot. However, the CD drive is another story. Jumpin' Jehosephat! That looks like an all-day affair! I build PCs all the time and generally feel comfortable digging into the hardware, but could someone point me to some good docs on the procedure? It should be similar to the Blue and White G3 since they are essentially the same machine (Yikes mobo G4 350).
