GIGABYTE GA-X150M-PRO ECC Kingston 16GB ECC DIMM KVR21E15D8/16 Pentium G4600 CPU
Toys arrive in a couple of days. Total outlay was $220.
When I first built my storage box, in 2009, the AMD CPUs all supported ECC DRAM, but I could not find a motherboard-chipset-BIOS setup that would actually implement it.
The closest to a classic HP Microserver is the SuperServer 5028A-TN4, although that one uses the Atom chips that have been recalled.
There's also the much more powerful SuperServer 5028D-TN4T.
They also have a bunch of older models whose names escape me, but can be found by searching for "supermicro mini tower".
It's okay as a NAS that mostly sits idle and occasionally serves up unencrypted data at GigE speeds or less. For more demanding tasks, it's woefully underpowered.
Still, a box is a box :P
Of course it always depends on the use-case, but for most people at home it's sufficient. I use it as a Minecraft and media server.
You sure? Around that time I plumped down a Phenom X4 and ECC RAM on an ASUS board, and I thought it supported ECC - the chipset was AMD too.
