That's exactly the point. Forking over almost 500 bucks for a low profile but low end computer to put disks into, while making it easier for less technology "risk taking" people to achieve some self-hosting features, when adding about 100 to 150 more you can actually get over 4 times the power any of those things can give you, kind of looks like a huge waste of money to me.
I made that mistake once. I outgrew my QNAP in less than a year, so I ended up passing it over to my sister since she doesn't tinker at all and uses it exclusively for backing up her data, nothing else.
I self-host nextcloud, bitwarden, have a cloudflare tunnel set up to avoid opening ports in my PFSense, I host my own Wireguard, AdguardHome, Bitwarden, Joplin, Home Assistant, 2 search engines (SearX and Whoogle), and many things more.
