FreeNAS build tips

[matrix07012]

So, I would like to build a NAS for home use with FreeNAS as the OS in the near future. I already picked most of the parts, but I am unsure about the case and the motherboard. FreeNAS recommends a server board from Supermicro, but that thing is 255 USD. Is it worth it? It will be on 24/7, but it wont be under a constant load. And the case is really expandable, but I will never need a space for 15 drives. So what would be a good case for 5 drives?

 

Here is what I got so far:

CPU: Intel Pentium G3258 3.2GHz Dual-Core Processor  ($64.89 @ OutletPC) 

CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler  ($24.98 @ OutletPC) 

Motherboard: Supermicro X10SAT-O ATX LGA1150 Motherboard  ($255.99 @ SuperBiiz) 

Memory: Crucial 16GB (2 x 8GB) DDR3-1600 Memory  ($109.99 @ Newegg) 

Storage: Crucial V4 32GB 2.5" Solid State Drive  ($35.95 @ Amazon) 

Storage: Western Digital Red 4TB 3.5" 5900RPM Internal Hard Drive  ($148.98 @ OutletPC) 

Storage: Western Digital Red 4TB 3.5" 5900RPM Internal Hard Drive  ($148.98 @ OutletPC) 

Storage: Western Digital Red 4TB 3.5" 5900RPM Internal Hard Drive  ($148.98 @ OutletPC) 

Storage: Western Digital Red 4TB 3.5" 5900RPM Internal Hard Drive  ($148.98 @ OutletPC)
