A lot of brands offer really good computers that will last for years. I have a desktop model that I've had for nine years, and although the hard drive gave out, it's been repaired and runs as well as it ever did.
Sony is a great brand to use and lasts years.
IBM is credited with originating desktop virtulization over thirty years ago. It allowed their mainframe computers to be more efficiently divided among users.
ASUS is one of the top manufacturers of affordable desktop computers. They can be purchased from the ASUS website or one may choose Dell, Overstock, and Amazon.
There isn't an advantage to a G4 desktop as it is old technology. Apple stopped using the microprocessor in its computers more than 5 years ago. It's better to go with a more up-to-date processor.
The Mirena IUD lasts five years, Paragard lasts 12, and Skyla lasts three years.
If you want to just replace the entire thing cheaply, try Wal-Mart. They carry a very basic brand of laptop and a desktop model, both by Dell. These computers will last a good few years, just be sure to keep security downloaded at all times.
The contraceptive implant lasts three years, and the IUD lasts five or ten depending on which one you choose.
Computers 50 years ago weren't really "computers" as we know them. Mostly anything that used a CPU appeared more mechanical/electrical than a stand alone desktop or personal computer. (Things that used a CPU were machines that didn't look anything like computers) Now just look at your smart phone, or go check out the ipad (apple.com) Computers now give us a better picture of what is, what should have been and what will be.
The Compaq brand dates back almost 30 years, and has used a large variety of processors in that time period.
lasts 2 years and starts every Jan 3rd of odd years (2003,2005, etc.)
