I converted mine at no penalty when I left my last job. Not a lawyer, YMMV, etc. Edit to add I think I moved from a 401k to a "self directed Roth IRA" with everything moved into gold and silver. Broker told me not to mess with silver, too costly to store and in fact I only got 1000oz which I thought was way too low but he talked me into more gold. Oh well. Buy silver!
