Or, go fanless. For hard drives, SSDs are looking good.
I love being able to move up to a better technology. Sometimes an otherwise good product has a weakness that causes early failure. Most people throw the whole thing away and buy another one. That is often a sensible thing to do. But sometimes an upgrade can modernize an old product enough that it's still worth keeping and using. Haven't been able to do much of that with computers, they change so rapidly and radically in such short times. I have a 200M hard drive that's still good, as far as I know. Too bad it's pretty much useless. But for other products, have had somewhat more success.
I have kept a front loader washing machine in good working order through 3 failures. First, a defective Hall effect sensor, fairly easy and cheap to replace for $20. Then the "spider", the piece that attaches the motor to the drum, was made of die cast metal that quickly corroded upon exposure to the water and detergent, breaking after a few years of being weakened. (The idiots at LG who pulled that stunt thought they could get away with being cheap there.) We got a new spider and had it coated. Finally, the door seal became moldy, and we replaced it. We now know that the door should be left open between washes, so it can dry out.
It's similar with cars. 1960s cars were good for as little as only 50K miles. It used to be remarkable to get the odometer to roll over. Upgrade a few things, and those old cars can last far longer. About the first high maintenance item to toss is the ignition system. Points have to be replaced at least every 10K miles, but one of the early solid state systems, so that you don't have to add a computer, can last the life of the car. Whenever an incandescent bulb goes out, replace it and every other one within reach with an LED. A big help is that lubricants have gotten much better. Even if you don't modify anything at all, old cars last longer just by using modern motor oils and the cleaner gasolines of today. Aftermarket parts often benefit from superior understanding or better availability of better materials, and can be much better than the originals. For instance, the original brake pistons on this 1960s car were chrome plated steel- they called that "hard chrome", as opposed to the "soft chrome" used for a bumper. Nevertheless, the plating eventually wore through, and the pistons began to rust and stick. I thought I'd just get them replated, but no, they make pistons out of stainless steel now. Much better. One reason for this change is that over the years, other improvements in metallurgy, mining, and trade, have made stainless steel cheaper. I am eager for the day of the electric car, which may be sooner than the year of Linux on the desktop. Electric motors are far simpler, more reliable, more efficient, smaller, quieter, and all around better than combustion engines. Good enough batteries will enable electric cars to sweep gasoline and diesel completely off the market, the same way that flat screen monitors swept CRTs away.
