Build in Intel® Celeron® Processor 1037U - has more power, than any Atom out there. It has  TDP at 17W, but, unfortunately, there are no AES-NI instructions. You will get 4 SATA ports, support up to 16GB of ram, and one PCI or PCIE for further upgrades.

Price: not more than 80$.


RAM: 16GB

It will be cheaper in a long run to buy 16GB.

Price: used 75$

Disks:
2x2TB

WD green serie will be perfect, as a starter. After that, I can add additional 2 drives, or 4 drives with expansion PCI/PCI-E card if needed.

Price: used 120$


Power Supply:
350W+ BeQuiet, Enermax, Chieftec, Fortran, etc

The most important part is certification Bronze 80+ or more.

Price: Refibrushed 30$

Case:
Old Antec, Zalman, Fractal, etc case.

Including LCD Panel and Dust filters.

Price: used 30$

Pendrive:
16GB Sandisk

It must be small as possible. FreeNAS does not require it, I am.

Price: 7$

Total: ~340$
