It is still probably a good idea to have the main equipment running on radiation hardened hardware, while the more unimportant stuff runs on off the shelf components. That way at least if something goes wrong with the non-rad-hardened equipment, it could be rebooted or debugged using equipment which is rad-hardened I'm no scientist but that's my take on the matter.
