Of course, external SCSI enclosures are quite standard in Server environment, and single disk cases are quite cheap on ebay... So SCSI will work without problems. Booting from other external disks depends on the technology: When there are enclosures, that map themselves as SCSI, like some IDE things, yes. With Serial ATA, we also will see some external storages, once fitting controllers are widespread. But what you have in mind, is probably USB and firewire. This depends on 2 things: 1) The BIOS of the PC has to know about these devices, and has to try to bootstrap from them. 2) the OS has to know, that it is run from a different device like traditional IDE/SCSI, because USB looks different. As far as I know, FreeBSD is not capable of fully booting from external USB storage, but I haven't followed the development in the last few months there.
