I remember that my old HP nc8430 from 2006 cost only 20 Euro some 10 years later. I could have bought a couple of them for spares if I planned to keep it running. The problem was that the GPU run out of software support circa 2012 and I had to pin the Linux kernel to a 3.1x version. An open source driver apparently made it into the kernel many years later but I never checked if it actually works. I bought a new laptop in 2014 which is a kind of Frankenstein on its own nowadays. I replaced the screen (a defective hinge under warranty), the RAM (maxed it out at 32 GB), the HDD with a 2 TB SSD, the DVD burner with another SSD, the keyboard many times as it wears out and maybe that's it.
