Sure!
Yes, see, in my case price is *really* compelling.
Buying two new 12TB drives for my current box would add 4TB of storage and cost me €600 at best. Most likely more than that.
At little more I may get a Gen10+ + NVME+PCIe Adapter + 8TB drive.
And, in the process
- renew 10year-old hardware
- decrease occupied physical space
- gain more storage flexibility in the future.

Really compelling.

Thing is, so far replacing HDDs (in couples, as I liked havign a simple mirror in my home server) has been quite OK because prices of mechanical drives kept decreasing quite fast.
Not these days. Mechanical drives are quite expensive, all considered. So the whole economics has changed, as far as my personal approach to home server goes. I'd better have some more flexible storage that costs me a little (lot) less when in need of expansion.
