This article inspired me to look and see what this computer is. Apparently it is a "AMD Athlon(tm) II X2 250 Processor" from 2009. So 17 years old. It has 8 GB of DDR3 memory and runs at 3 GHz. It currently has OpenBSD on it, but at least one source thinks it could run Windows 10.
The fact that I didn't know any of this is what is significant here. At some point I stopped caring about this sort of thing. It really doesn't matter any more. Don't get my wrong, I am as nerdy as they come. My first computer was a wire wrapped 8080 based system. That was followed by an also wire wrapped 8086 based system of my own design I used for day to day computing tasks (it ran Forth). If someone like me can get to the point of not caring there is no real reason for anyone else to care.
Your electricity bill alone could justify the cost of a new computer purchase if you're not shutting that down after every session.
An interesting point. Some random measurement gets 49W idle[1] which is probably close enough. I don't constantly compile stuff or stream video. At my local electricity rate of $0.072/kWh that works out to $31USD/year.
New systems idle at something like 25 Watts according to a lazy search. So 49-25=24W. That works out to $15/year hypothetically saved by going to a newer system. But I live in a cold climate and the heating season is something like half the year. But I only pay something like half as much for gas heat as opposed to electric heat. So let's just knock a quarter off and end up with 15-(15/4)=$11.25USD hypothetically saved per year. I will leave it here as I don't know how much the hypothetical alternative computer would cost and, as already mentioned, I don't care.

65W TDP? Let's say we want to run a PC so we're switching to a newer low-end Ryzen with a 35W TDP and that that's a 30W difference for the whole system. Let's say we're running the system 24/7 and the CPU is pulling its full TDP constantly. Average US residential electricity price is $0.18/kWh.
0.03 kW * 24 h * 365 d * $0.18 = $47.30/year
In the UK, residential electricity tariffs are currently capped by the regulator at 27.69p per kWh, resulting in a total yearly cost of £72.77. Much higher than in the US, but still much cheaper than a new PC.

PC power draw at the wall is different than TDP. Idle power goes to a lot of components.
Even CPU TDP is not an accurate measure. My latest AMD CPU will pull more than it’s rated “TDP” under certain loads.

So $50/yr for 4 years gives you ~$150 with $50 extra for shipping or whatever, which gets you a decent Lenovo M700 Tiny with much better performance in both power and power consumption.

Watts in TDP are not the same as watts in electricity, although they're both measures of energy.
TDP is a thermal measurement, it's how much heat energy your heatsink and fan need to be able to dissipate to keep the unit within operational temperatures. It does not directly correlate to the amount of electricity consumed in operation.

Someone's never tried to locally compile a Rust program. :)
Did any of the components fail over time?
HDD/SSD?
Pretty surprising to have this thing still be working 17 years later, unless it spent a good chunk of that in 'cold storage'.
Well it has a SSD in it now so it must have gone through at least one actual hard drive...
