I name my PC's. Makes it easier to keep track of them. And the name follow the motherboard, with the name being based off some feature or overall aesthetic.
The last home-built I had was "Bertha" who became "Big Bertha". Bertha started as a Pentium 4 2.8GHz Prescot in ~2004 IIRC. High-end Asus mobo which supported 10 drives natively. At some point I added Matrox professional video encoders & rendering cards, which caused Bertha to outgrow her case, so a second identical case was strapped onto the side to house the drives, more hardware, and more power supplies. 6 streams of HD video, with 10 layers of effects, all in real-time, full quality. Beyond that and it'd start to render, which was still amazingly fast for its time.
Big Bertha was responsible for half my electric bill, and I lived in an all-electric condo...in Florida.
She "died" in 2012 when the BIOS chip gave out. It had been acting up, but I rebooted once a year so it wasn't an issue. In 2012, she wouldn't power back on.
