Moving farm from Windows 2008 R2 to Windows 2012 (R2?)

I've been asked to move our current small SP2010 Server farm (WFE, App, and SQL) from Windows 2008 R2 servers to new Windows 2012 servers.

Any limitations that would prevent this from happening? Any major differences? Installation through the GUI won't be a problem? Any benefits to tout? I've installed 2012 R2 on a HyperV but haven't messed around with it much beyond that.

Thanks,

Scott
