@MythicNation @hp @cstross Unless you need to run an up to the moment game, you do not need recent hardware.
This fanless browsing box is a second hand Optiplex 3000 thin client (Wyse 5070 is also good). It has 32GB RAM and 1TB NVMe. Not good for games though.
My main system is a dual Xeon system that is really high end - for 2013. Plus a 2017 graphics card.
My lounge gaming system does have a 2024 GPU, it is in a second hand workstation from 2018 and is fast enough to run VR.
I'm considering getting another workstation system, to run bleeding edge Unix releases. Likely to be a second hand 2016 workstation, cost of up to 300 quid.
There are disadvantages with this such as increased power consumption, proprietary power supplies and cabling, but it's often also possible to hack the BIOS to add in NVMe support and resizable BAR support if they're not included (obviously check before buying, and some Dell systems don't support turbo boost properly)
