I'm an not the relentless explorer and experimenter that you're sort of patronizing with this comment. I'm somebody who knows that you can put together a NAS with an old desktop somebody will give you for free, slap Debian Stable on it, RAID5 (4 or fewer) or RAID6 (5 or a few more) a bunch of drives together, and throw a samba share on the network in less than a day (minus drive clearing time for encryption.)
It is not some sort of learning and growing experience. The entirety of the maintenance on the first one I put together somewhere between 10-15 years ago is to apt-get update and dist-upgrade on it periodically, upgrade the OS to the latest stable whenever I get around to it, and when I log in and get a message that a disk is failing or failed, shut it down until I can buy a replacement. This happens once every 4 or 5 years.
The trick with big-name NAS is that they go out of business, change their terms, or install spyware on your computer and you end up involved in tons of drama over your own data. This guide is even a bit overblown. Just use MDADM.* It will always be there, it will always work, you can switch OSes or move the drives to another system and the new one will instantly understand your drives - they really become independent of the computer altogether. When it comes to encryption, all of the above goes for LUKS through cryptsetup. The box is really just a dumb box that serves shares, it's the drives that are smart.
I guess MDADM is a (short) learning experience, but it's not one that expires. LUKS through cryptsetup is also very little to learn (remember to write zeros to the drive after encrypting it), but it's something that turnkey solutions are likely to ignore, screw up, or lock you into something proprietary through. Instead of getting a big SSD for a boot drive, just use one of those tiny PCIe cards, as small and cheap as you can get it. If it dies, just buy another one, slap it in, install Debian, and you'll be running again in an hour.
With all this I'm not talking about a "homelab" or any sort of social club, just a computer that serves storage. The choice isn't between making it into a lifestyle/personality or subscribing to the managed experience. Somehow people always seem to make it into that.
tl;dr: use any old desktop, just use Debian Stable, MDADM, and cryptsetup. Put the OS on a 64G PCIe or even a thumb drive (whatever you have laying around.)
* Please don't use ZFS, you don't need it and you don't understand it (if you do, ignore me), if somebody tells you your NAS needs 64G of RAM they are insane. All it's going to do is turn you into somebody who says that putting together a NAS is too hard and too expensive.
* my original post was in no way intended to be patronizing - it was merely to point out that before investing effort, it pays to understand one's goals and priorities :-). Some activities have rabbit holes, which are fun, but only if you're into that sort of thing.
* now though, I will indulge in pointing out my absolute favourite hacker news type of post : "how dare you insinuate this is tricky or difficult or time consuming for anybody - you merely [series of acronyms and technologies and activities nobody in my family could do after a month's study, while hand waving over risks and issues and costs]" 0:-)
Id also argue if you can setup md you can probably figure out how to setup zfs. It looks scary on the RAM, because it uses “idle” ram, but it will immediately release it when any other app needs it. People use ZFS on raspberry Pi’s all the time without problems.
