I disagree with this. I replaced my original G4 450 Cube with a G4 1.25GHz Mini. The laptop spec drive on the Mini failed within two years. So, I bought another G4 450 Cube off of eBay, put 1.5GB of RAM and a Twin View in it, hooked it up to a lucite 23" Cinema HD Display, and am again happy as a clam. I also got the small Apple Wireless Bluetooth Keyboard, a MiniStack external drive and USB/Firewire hub (With the D-Link Bluetooth dongle), plus the Mighty Mouse with it. It runs OS X 10.4.11 flawlessly, is quieter than the Mini (Still no fan), and replacing drives when they fail is easy. Of course, it has an original AirPort card, so it connects via my AirPort Extreme BS flawlessly, even with my newer computers connected at the same time (I actually have an original G4 400 TiBook also, which is still mint and going strong). As a backup to my primary system and an entertainment system in my bedroom, it's perfect. I even have the old Firewire version of EyeTV and my Sat system running into it, so I watch TV on it when I'm in bed. Lastly, I moved my old Digidesign M-Box to it, and it runs ProTools LE 7.4 perfectly as well, letting me record basic tracks in my bedroom for a change of environment from my main recording system. The Cube is the coolest computer Apple ever made. The Mini isn't. As far as the processor upgrade, I think the SLOWEST Sonnet that will allow OS X 10.5 to run on the Cube - the 1.2GHz - would be the way to go. The faster the hotter. I see those pop up on eBay every now and then, but always at a time when I'm short on cash in my PayPal account. LOL!
