Perhaps, but I don't really get the dozens of TB of storage in the home use case a lot of the time either.

Like if you have a large media library, you need to push maybe 10MB/s, you don't need 128GB of RAM to do that...

It's mostly just hardware porn - perhaps there are a few legit use cases for the old hardware, but they are exceedingly rare in my estimate.

> Like if you have a large media library, you need to push maybe 10MB/s,

For just streaming a 4k bluray you need more than 10MB/s, Ultra HD bluray tops out at 144 Mbit/s. Not to mention if that system is being hit by something else at the same time (backup jobs, etc...).

Is the 128GB of RAM just hardware porn? Eh, maybe, probably. But if you want 8+ bays for a decent sized NAS then you're already quickly into price points at which point these used servers are significantly cheaper, and 128GB of RAM adds very little to the cost so why not.

For 8+ bays you just need a SAS HBA card and one free PCI-E slot. Not to mention that many motherboards will have 6+ SATA ports already.

If anything, 2nd hand AMD gaming rigs make more sense than old servers. I say that as someone with always off r720xd at home due to noise and heat. It was fun when I bought it during winter years ago, until summer came.

I've been turning off my home server even though it's a modern PC rather than old server hardware because it idles at 100W which is too much. Put a Ryzen 7900X in it.

Not sure if it's not properly doing lower power states, or if it's the 10 HDDs spinning. Or even the GPU. But also don't really have anything important running on it that I can't just turn it off.

And what case are you putting them into? What if you want it rack mounted? What about >1gig networking? What if I want a GPU in there to do whisper for home assistant?

Used gaming rigs are great. But used servers also still have loads of value, too. Compute just isn't one of them.

Maybe one of the Fractal Designs cases with a bunch of drive bays?

> What if you want it rack mounted?

Companies like Rosewill sell ATX cases that can scratch that itch.

> What about >1gig networking?

What about PCI Express card? Regular ATX computers are expandable.

> What if I want a GPU in there to do whisper for home assistant?

I mean... We started with a gaming rig, right? Isn't a GPU already implicit?

Have you looked at what they cost? Those cases alone cost as much as a used server. Which comes with a case.

> What about PCI Express card? Regular ATX computers are expandable.

As mentioned higher up, they run out of lane count in a hurry. Especially when you're using things like used Connect-X cards

		A rackmount case from Rosewill costs a couple of hundred bucks or so, new. And they'll remain useful for as long as things like ATX boards and 3.5" hard drives are useful. I mean: An ATX case can be paid for once, and then be used for decades. (I'm writing this using a modern desktop computer with an ATX case that I bought in 2008.) PCI Express lanes can be multiplied. There should frankly be more of this going on than there is, but it's still a thing that can be done. Consumer boards built on the AMD X670E chipset, for instance, have some switching magic built in. There's enough direct CPU-connected lanes for an x16 GPU and a couple of x4 NVMe drives, and the NIC(s) and/or HBA(s) can go downstream of the chipset. (Yeah, sure: It's limited to an aggregate 64 Gbps at the tail end, but that's not a problem for the things I do at home where my sights are set on 10Gbps networking and an HBA with a bunch of spinny disks. Your needs may differ.)
