It's the end of an era. A house power outage killed this dusty motherboard which had been running in a Linux (Debian) server nearly non-stop since 2011. The CPU is a Q6600 (Core 2 Quad) + 4GB DDR2 RAM.

The replacement is an i3-9100 board + 8GB RAM for £75 off Ebay; so the server's caught up to 2019!

The board change was mostly easy. The main issue needed booting from USB to fix the IDs for the 2 x RAID 1 arrays as they'd changed and confused the boot process. Glad I wasn't running Windows!

Did a quick bit of checking....

CPU/Core i3-12100F £84.99
8GB DDR4 RAM 3200MHz £67.00
Intel CPU Cooler £12.32
Gigabyte H610M motherboard £65.64

Total: £229.99

That makes the second hand board incl. RAM for £75 seem like a good deal - and it's all passed a very thorough burn-in period.

I'll keep an eye on CPU temperature to decide whether to replace the thermal paste but, as is, why disturb it.

BTW: I couldn't just buy a cheap NUC-type thing as there's 4 x 6TB HDDs in the current case.
