Upgrading the TPM in HP Small Form Factor PCs for use in Linux
I’ve recently bought a few Small Form Factor PCs on eBay to use as part of my backup setup.

Used Hard Drives from Tech on Tech
Updates July-2024 (5 month) update - no failures on any drives. August-2024 (6 month) update - still no failures on my drives from tech on tech, but I had another of my original Seagate Exos NAS drives fail - that’s now a 100% failure rate in less than 4 years. I recently had a drive failure on my NAS. While not a big deal with RAID-6, it wasn’t the first in that array, and the array as a whole was more than 3 years old.
