I had a old Acer SFF desktop machine (circa 2009) with an AMD Athlon II 435 X3 (equivalent to the Intel Core i3-560) with a 95W TDP, 4 GB of DDR2 RAM, and 2 1TB hard drives running in RAID 0 (both HDDs had over 30k hours by the time I put it in). The clunker consumed 50W at idle. I planned on running it into the ground so I could finally send it off to a computer recycler without guilt.
I thought it was nearing death anyways, since the power button only worked if the computer was flipped upside down. I have no idea why this was the case, the computer would keep running normally afterwards once turned right side up.
The thing would not die. I used it as a dummy machine to run one-off scripts I wrote, a seedbox that would seed new Linux ISOs as it was released (genuinely, it was RAID0 and I wouldn’t have downloaded anything useful), a Tor Relay and at one point, a script to just endlessly download Linux ISOs overnight to measure bandwidth over the Chinanet backbone.
It was a terrible machine by 2023, but I found I used it the most because it was my playground for all the dumb things that I wouldn’t subject my regular home production environments to. Finally recycled it last year, after 5 years of use, when it became apparent it wasn’t going to die and far better USFF 1L Tiny PC machines (i5-6500T CPUs) were going on eBay for $60. The power usage and wasted heat of an ancient 95W TDP CPU just couldn’t justify its continued operation.
The X3 CPUs were essentially quad cores where one of the cores failed a quality control check. Using a higher end Mobo, it was possible to unlock the fourth core with varying results. This was a cheap consumer Acer prebuilt though, so I didn’t have that option.
