Well finally sercummed to one of these babies primarily as my Buffalo Linkstation NAS is about full + the drive is at least 6yrs old. It's been faultless in this time (touch wood)!! So intending to install WHS 2011 on the N40L with 2x WD data drives in a Raid 1 configuration. First obstacle - bodging a DVD drive in to install the OS or a USB flash stick of sufficient size :> Tim..
