There are companies selling off PCs that are "too small" for Win11, really cheap. More than sufficient for a NAS. You might even get a bunch of them, chose the best mainboard/case/PSU set, put the others in storage, and get all the RAM and HDD in one box.

Stop ordering from Amazon
“… order from here instead [insert alternative]”
I use Intel NUCs off eBay for this kind of stuff. A few years ago you could get one for ~$200 on eBay.
Ask your local university facilities department about their overstock policy. The university of Arizona literally has a warehouse where you can peruse their old computers and furniture and buy at Craigslist prices.
Thinkcentre Tiny, Dell Optiplex Micro, or HP ProDesk Mini. Prices have gone up the last few months but they’re still a solid value. Most sellers ship pretty quick these days.
Thats my setup. Second hand lenovo m900 tiny for 100€, nvme ssd 2tb for 200€. Running immich, navidrome, dawarich, opencloud without problems
Not much right now due to LLM training hogging all of the memory across the industry. Best bet is lightly used.
For a server like this 4GB of DDR4 is enough. And that is cheap still.
Possibly, but it's going to have issues. Immich can run on 4GB if you disable machine learning features for image recognition and such. And Jellyfin can run on a minimal system with 4GB if you have a graphics card, but with integrated graphics likely to be in a sub-$300 system the recommend 8GB. And graphics cards are still expensive even after the crypto craze has settled because LLMs benefit but also because of the artificial memory shortages they've created. Running both might work if you set a lot of virtual memory and never have them operating at the same time so it's not swapping constantly. And that's not leaving room for the other stuff. I'd say you could squeak by with 16GB, but that's going to be most of the budget even for low-end, off brand sticks that are available right now.
Any used PC or laptop that can run Linux.
Where you happy with the Lenovo thinkcentre? You can often find replacement motherboards for these. It will be cheaper than any of the alternatives here.
It won’t be on Amazon, but I found a ton of older generation Mac minis available on Craigslist in my area. I picked one up for $50 and installed Ubuntu server. Thing’s been running like a champ for 2 years.
Edit: should have fully read your post. No idea about installing truenas on it. I’d assume most would be single ssd machines.
+1 on Mac mini as well. I just checked OfferUp in my area and M1-M5 are insanely expensive ($500+, M1 coming out about 6 years ago) but really good machines especially for their size and decent on power consumption too.
But downside of a M series is either you run macOS or Asahi Linux and nothing else yet.
So go for the Intel Mac Minis which are much cheaper and can run nearly any Linux distro with little to no issues as you would on a Windows PC. I’m seeing $50 range in my area as well. Older are good because RAM can be upgraded on some of them, but not all. Would be wise to do research on whichever seems right.
A word of warning on Linux on Mac though. Oftentimes there can be weird quirks with power management and suspend/hibernate. For a server though I guess that point is moot.
Just about any of the Intel N series minipcs are often suggested for just Jellyfin. I haven't looked at them too much yet.
A mini PC could certainly work! If you're willing to go ebay, I'd recommend any of these Lenovo Thinkcentre SFF PCs:
1-2x m.2 slots, 1x 2.5" slot, and some can accommodate a half-height PCI-E card in place of the 2.5" slot. Presumably, you'd want to go Intel for QSV
Yissss I got a bunch of tinys for 50USD each. I5/16GB DDR4/256GB NVMe. They run home theater computers and Linux servers AMAZINGLY. I would have bought more if they had more available.

Set aside some for surge protection/UPS
Find something on craigslist or local pickup on ebay, check government/police surplus, or do some freecycling. At least in my area a lot of people leave their e-waste computers at Best Buy, often in the doorway, nobody cares if you come and pick them up. Even if they're broken (and they're often perfectly functional and sometimes surprisingly powerful) it likely only takes a few before you've got some functional combination of parts.
It's likely not as much of a picker's heaven anymore since I imagine the huge wave of windows-10-obsolete computers being thrown away for no reason has probably mostly subsided, but there is so much old and perfectly functional stuff out there it's really unjustifiable to be buying something new especially at today's modern prices.
I purchase a bunch of machines off government auction, patch then up, and pass them back out for very little. Anything with 4 cores and 8 GB memory should do it. If you can get something with DDR4, that's a big step. Bonus points of it was made after 2018.
If you want a NAS on the cheap my preference is just get any cheap "normal" PC, a case with a good amount of HDD bays. Move the drives into the PC, and you have all the expand ability you could dream of. You can find plenty of DDR4 machines for cheap now. Then as ram prices come down you can go up to 128gb of ram as long as your board has 4 slots.
Anything on craigslist/FB marketplace will work.
This is the ticket. I got an enormous case in trade with a hoarder buddy, used mobo/cpu on ebay, new cheapo PSU, etc
Still just have 3 drives in but space for like 10 of them once I install the 2x cd bay hdd holder that fits a few more drives.
So a trick for the double drives is to pop in a low profile usb drive and install the os on that. Then you can use the ssd/hdd for other things.
Make sure the OS is good for that, or you use a very high endurance USB drive, or you use two drives in a mirror and are prepared to replace them. Most USB drives are not designed for constant use, like the log writes your OS will be doing.
So you leave the usb plugged in for boot and then you are good after that?
Yup! If you installed the os on it.
So you have one usb with the iso flashed to it and a second to install the os on. Use the first to install to the second.
Any post-2015 laptop would work. Look around in your local recycling bins :D
The key here is old hardware. I built a TrueNAS box out of an old Dell Optiplex 990. I got it from a friend for free but you can find one online for well under $200. Later you can upgrade the box bit-by-bit if you care to. I upgraded the case, motherboard, cooler, and power supply over time. It’s been a capable NAS for several years even though it’s using a 2nd gen Intel core i3.
I do what you are asking about literally with a 2014 Thinkpad. The only thing is I don't use any "fancy" features. For instance, with Jellyfin I ensure that the data is in a commonly supported format to ensure there is no transcoding or remuxing performed by the server itself.
So, just find any computer made in the last 7 years, slap Linux on it, and I'm sure you'll be fine.
Woot.com has lots of refurbs around that price.
It's part of Amazon so you can use your Prime shipping.
You actually can use a minipc. Minisforum has their NAB series and those have a slot in their internals for an SSD and they have an NVME slot in the motherboard. I found a NAB9 with an NVME, SSD, and 16GB of ram for around $310. So I would look for used NAB6s (cheaper than NAB9) on EBay. You should find some for under 300 with the Data SSD and NVME.
Openmediavault might be an option also, if the drive thing is a problem with TrueNAS
Hit up local government auctions. Sometimes they sell 2-4 computers in a lot, sometimes they sell 157. I got 4 Lenovo mini computers for $34 each in an auction a while back. They only needed hard drives.
