I think what I might most likely do is build a linux box with good RAID, toss ubuntu on it and install PS3 media server.

Ubuntu already has everything Open NAS has, and I can use PS3 media server.

One of the problems I have is that the HD video off my camcorder doesn't play natively on the PS3. So, if I bought an off the shelf NAS I'd have to transcode the video before storing. PS3 Media server transcodes it on the fly, and works great.

Hey I'm an F'n Jerk!
