Not specifically, no. When I did change to building my own NAS, I cracked open my older 4TB backup drive to use as a spare.

Indeed. That's how I populated my NAS with 3 10TB drives and saved around 120 dollars total, and this was 4 years ago.

These are the ones I got: https://a.co/d/8x58jBY

The only extra thing was disabling the 3v pin, and that was it. Been running rock solid all this time.

Just make sure to research what disks are in the external housings you're planning on getting, as not all drives need to have pins removed/covered.

I think I'd buy 2nd hand quality server drivers before I'd shuck.

I did once. Well, more along the lines of "what did i buy this thing for, can use the HDD as is". The HDD had additional contact points at the bottom. Don't remember if they worked as is and what i did with them.

Personally I think it's a bad idea

There's lots of things that can go wrong and most of the time those drives are made in super controlled environments because they can be extremely sensitive. It's just not worth the headache
