Great post. I just revived an old PC as well that was gathering dust by installing Linux on it. Also upgraded the hardware from a i3-6100 using iGPU + 8GB RAM to:

- i5-6600K (€20 used)

- ASUS STRIX RX 480 8GB (€20 used)

- 16GB DDR4 (€50 used)

€90 all in for an incredible Linux machine that still runs games great at 1080p. Probably even that amount of RAM was overkill, but it's 3200Mhz instead of the old 2133Mhz.

That's 90 for just the upgrade, not the whole PC, and that Rx480 won't run recent AAA games on 1080p, maybe just older games.
