Server 2008r2+Flexraid view?

[Knuckle-Head]

I was building an upgraded Vail home server when I realized Vail was not for me.

My hardware->
Norco 4220 chassis
Supermicro X8sil-f-o
Xeon 3440
Kingston KVR1333D3E9SK2/4G
2xSamsung f4 hdds (so far)

I'm kicking around the idea of running server 2008r2 w/ flexraid view. My main use is movie storage. Perhaps also as something to back up my other desktops. I would also like to use it to run handbrake and rip directly to .mkv...
Any input?

I'm really leaning to just keeping the original WHS and play with flexraid...

Thanks!!
