Dunno if anyone else but me knows anything about these, but ive seen a few of you are computer people as well as car people lol

Ive got a HP Mediasmart Home Server (EX470) and just recently the OS has taken a poop and is giving me some grief with the CPU Fan.

So im replacing the fan and was gonna do a nice fresh install of Windows Home Server, and thats where my question comes into play.. I have the "original" WHS version included with my HP restore CD's etc..
but I was thinking of trying out WHS 2011.. Ive heard some mixed info about it becuase of the drive extender issues etc..

Does anyone here have any experience with WHS 2011? Should i do it? or just stick with what HP gave me?

Thanks
