I have also got one of these
IDE to SATA or SATA to IDE Adaptor : Internal SATA Cables : Maplin Electronics
and makes my old ide/ata 200 250 and 300GB disks both hotpluggable to the Microserver but also bootable off them via that adapter
good way to get some extra life out of the old disks ie for test boot purposes or playing with and testing raid configs etc
