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.
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.
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.
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.
Still, a box is a box :P
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".
