I am using a desktop pc I built in 2012 for around 350 USD. It's running 24/7. I had to replace the mainboard, psu and ram over time due to failure (with similarly old components). The CPU AMD A10-5800K is still going strong though.
Eh, honestly, depending on where you live your yearly electricity bill might justify an upgrade considering you’re running it 24/7. You might want to check your idle wattage with a kill-a-watt and look at your price per kw hour on your electric bill.
Basically you can outperform that rig with an Intel Atom N100 with 1/10th the TDP of the A10-5800K. You could jump on Amazon and grab a Beelink mini PC or similar for about $200 and have an entire system that maxes out at 35W, idles at about 12-13W.
If you save 20W of power on your idle and your power costs 20 cents per KW/h the new system would pay for itself in less
than 6 years. If you’re in a country like the UK or Germany your payoff is 3 years or less.
