Server chronicles - upgrade RAM and HD to the System76

It is time to upgrade the System76 server.
The original configuration had 4 GB of RAM and 2 HD SATA in RAID 1 of 2 TB,

with the upgrade I'll bring the RAM up to 32 GB (the maximum  RAM this 7 years old mother board can handle) and I'll install 2 4 TB SATA HD in RAID 1 or 2.
