Newbie build

My Drobo 5N is full (5x4TB WD Reds) and when I looked at what it would cost me to change the drives out to 6TB I realized I needed to research alternatives (that and the horror stories of data loss after simple problems like the network plug failing). That's when I discovered unRAID!

My use is mainly for a Plex server with all the programs that go along with it (Sonarr, sabnzbd, Transmission, CouchPotato) and a simple file server as well as have some extra power if/when I decide to play around with unRAID's other possibilities without breaking the bank.

CPU: AMD FX-6300 ($98)

Mother board: Asus M5A78L-M/USB3 Micro ATX ($32)

RAM: Kingston HyperX Fury Black 2 x 4GB DDR3-1600 ($40)

PSU: Corsair Builder 430W ($20)

Case: Fractal Design Define Mini Micro ATX Mini Tower Case ($100)

How does this look?

Additional questions:

• Why does it seem like most people use Intel vs AMD. My reasoning is purely in pricing. Is there something Intel offers when it comes to unRAID I haven't seen?
  
• Obviously the memory isn't ECC. Do I need ECC?

It's okay.    The only thing I'd definitely change is the power supply => the CX series is a very low-end PSU that isn't near as good as Corsair's TX, HX, and AX units.    It DOES work ... but a quality PSU is not something you want to skimp on for a fault tolerant server.

Performance and efficiency.    A mid-range Core architecture CPU [e.g. an i5-4670 will significantly outperform the FX-6300 while using less power (and thus running cooler) ... and does this with only 4 cores, which means the per-core performance is a LOT higher.

... Obviously the memory isn't ECC. Do I need ECC?

It's certainly nice to have fault tolerant memory on a fault-tolerant server ... but it's not a requirement.    If you limit your system to no more than 2 installed modules, unbuffered non-ECC RAM is reasonably reliable.

Thanks for your input. I'm reevaluating my processor (and thus motherboard) and power supply. I appreciate the help!

Dont buy a corsair psu - they are not what they used to be!

Go for a EVGA
