The server I just built – it date to 2006. Which makes it at this writing eight years old. It’s had some upgrades etc. probably as late as 2009. So it’s of mixed age. But still perfectly functional.
That’s the thing – try installing Windows Server 2008 on this and it’ll puke. But put Ubutu Server 12.04-4 on it and miraculously it works. All that’s needed from this box is one year. I fully expect it will work because the until has sat for near three years un-powered. So this brings it down to only five years of actual operational time.
You get new life out of old hardware. This is sort of why I proposed recycling state I.T. gear – machines still usable wipe the disks and put Ubuntu on them. Older machines strip down and send for metal extraction as there’s quite a lot of gold in them. State would get residual value out of all of it and then not have to pay to warehouse it. Win-win.
