Sounds good, although I always worry about very large (over about 500GB) drives, if they fail when they're nearly full, that's a lot of data to lose if you don't have backups, and a lot of people don't
I back up and keep essential data on a pair of network Raid 5 arrays, which allow hot-swapping of failed disks without loss of data.
Much as I prefer Win7 over later versions, it doesn't update any more. Linux is the OS of choice here, and has been for many years.
