alt Hacker NewsAdjadent to the article, there are some interesting builds with pulled parts from decommissioned servers in places where hardware is expensive or heavily taxed.
There's an entire parallel ecosystem around Chinese X79 and X99 boards [1](brands like Huananzhi and Machinist). They exist almost entirely to soak up scrap-tier Xeons and decommissioned server DDR3 and DDR4 ECC RAM that get pulled from datacenters for next to nothing. You see them online in Russian/Chinese/SE Asian online communities as budget builds, so nearly all the BIOS mods and documentation are in Russian or Chinese.
I think in NA we'd tend to write this hardware off as e-waste unless you're a homelabber (though I know Kimsufi still includes DDR3 builds in their catalogue). But in emerging markets, people have been squeezing real utility out of discarded enterprise silicon for a long time out of pure economic necessity. I've been tempted to do my own build but I already seek to have collected an overwhelmingly unnecessary amount of 2012-era workstations that I'm not sure my partner would appreciate an addition to.

I have 2 Huananzhi EPYC boards.
At about $350 each, I had to try them. Everything else was double.
Only thing I can say so far is, they boot linux on second hand EPYC 7002 series CPU's.
Haven't put them through their paces yet. V
Oh, I remember quirk #1 ... apparently, only 1 of the case fan headers is speed controllable, the others run at full speed all the time, with no bios setting.
You can fix it with a fan hub that supports pwm so not a show stopper by any means, for those wanting to try these motherboards.
About six years ago (as a holdover until I went full homelab, which I never did) I built a machine with some spare parts, a $40 Xeon E5-2650v2 (8 core Ivy Bridge), and one of those Machinist motherboards.
Initially it was just for home server stuff (ZFS array for storage/backups, Plex, Vaultwarden, etc) but then I wanted to experiment with a remote dev environment using LXC/LXD.
I now do all my web development (mostly back-end, Python and C#) on that machine via tmux and VS Code remote SSH. I'm sure if I was running my browser on it it might painful given the slow single-core performance, but honestly I've felt zero need to upgrade it. Once the RAM-pocalypse is over I'll probably look at doing so just for reliability's sake.
I have one of these Machinist boards sitting in my closet, which I haven’t set up mostly out of laziness. What I really want is a PCI-E card that can take DDR3 RAM to be used as a RAM disk for containers that do a heavy amount of heavy I/O.
I imagine those countries have sane energy prices compared to Western Europe.
The E5-2670v1 was goated for this back in 2016-2017. You could get them for like 25-50 bucks. I still have one of the supermicro boards I got from work in hardware decommissioning and one of the chinese franken-boards with a modded bios.
There are significant performance/energy ratio problems with older hardware, particularly with the rise of ARM.
Until about 6 years ago I also mostly used ex-server "ewaste" hardware, because it's always been cheaper, except for electricity use which I wasn't paying for myself. My desktop in ~2015 was built from 2006-era hardware, with 32GB of ECC DDR2, which felt like a lot at the time.
My "6 years ago" build was with more typical current-gen consumer-grade hardware, because at that point I was on the hook for the electricity bill. I haven't thought about what my next build will look like because it's still going strong (aside from a flakey DIMM... so my next system will have ECC).
