Alright, so my goal in the near future is to put together a new HTPC to serve up 1080p video and uncompressed audio (primarily FLAC) to my home as well as to my mobile phone and my laptop when I'm traveling. The kicker is that I still want my storage to be in a RAID5 array. While I know this is possible, I am still playing with what my best solutions are to get the job finished, and make sure its finished correctly. I would still like this to be a low power/low heat machine and I am willing to spend some extra money to make it so. With that said I have two primary questions: 1) do you think the following hardware will be suffiecient enough to handle serving 1080p video and other high def media and maintain a 5HDD RAID5 array (5x WD Caviar Green 2TB drives is the drive of choice currently)? Here is what I had been hoping to use for hardware: Gigabyte GA-880GMA AM3+ mobo AMD Athlon II X4 610e Propus 2.4GHz Socket AM3 45W Quad-Core CPU SeaSonic X series SS-400FL Modular 400W PSU --- do you guys think 400W will be enough? G.SKILL ECO Series 4GB--- Not sure about this one so I am definitely open to suggestions and as mentioned, WD Caviar Green WD20EARX 2TB and 2) do you think I would be better off running FreeNAS virtually or running unRAID on top of a stripped Linux build? Any input would be greatly appreciated!
