My NAS, Sheila, received a substantial upgrade recently, and I took some pictures during the construction. The specifications are:
MOBO/CPU: AsRock C2750d4i
RAM: 16GB Kingston ECC RAM
CASE: Fractal Design Node 804
HDDs: 2x 4TB Seagate, 1x 2TB Samsung, 1x 120GB Intel SSD
Of which the mobo/cpu, ram and case are new. Enjoy.
