I found a Sun Ultra 20 M2 for $35 at the local thrift store, but someone has taken the big 120 MM fan out of it. Does anyone have one squirelled away? It's a 4 pin connector, and looks to have some kind of shroud with clips to mount it onto the case. I gave a fair bit of older Sun hardware to trade, or I'll pay cash if that helps. Cheers, Mike
