I have recently accquired a NEC powermate 2000 all in one lcd computer it uses a laptop size 2.5" HDD. It came without a HDD but the HDD connector sticks out of the side so i just want to be able to use a regular 3.5" hdd rather than having to shell out $ for the expensive 2.5" Hdd but I am not sure if its at all possible. If not is it possible to boot the system from a USB HDD, the Bios does not have a USB boot option. Its an intel 810 chipset celeron 466mhz 256MB cd/dvd. I have checked the machine with an old 1.2 gb 2.5" drive to see if the machine was in working condition.
