First off, I found this forum a few months ago when I was kicking around the idea of building a storage server for all my movies, music, etc. and after reading about unRAID system I decided it was the best option for my needs. I am an absolute beginner when it comes to building something like this and have very little experience in selecting hardware parts. I am looking to use this for media streaming using Kodi and possibly plex down the line. Here's a list of the parts that I have found so far and I wanted to get some expert opinions on my selections thus far. Case: Lian Li PC A76 ATX (Already Purchased) PSU: SeaSonic 520W 80+ Motherboard: ASRock FM2A88X+ BTC FM2+ AMD A88X CPU: AMD Athlon X4 750K Trinity Quad-Core 3.4GHz Memory: Crucial 4GB (1 x 4GB) DDR3-1600 Memory (x2) I was going to pick up 4 6TB WD (either Green or Red) hard drives to start with and expand as needed. Will I need a CPU cooler? Did I miss anything or get anything incredibly wrong? Thank you all, I've learned a lot from just reading the various posts throughout this forum. KC
