The problem was two 1000uF 10V capacitors in the PSU which had developed bulging tops and ESR greater than 1 ohm. Replacing these capacitors brought the system back to life. It would not be a surprise to see more capacitors fail in these power supplies due to the small space the Mini-ITX form factor requires several very hot power transistors to be crammed into.
