Hi
if you are good with a soldering iron and have knowledge about electrotechnics you may rework the US-PSU into a european one.
I have had a dead PSU in my 220V A3000T and the only PSU I could get was an 110V type. They are identically, there are only two wires changed in the 110V to the 220V type. I think the A3000 desktop has a simular build PSU and may also be reworked to 220V.
