The trouble was the external drive enclosures I found that the FW ports on the Genesys Logic inc. housings would not mount but the USB does. So I grabbed a couple of other enclosures and they work, So my beloved Cubes are actually up to snuff, But I do need a MOBO for the 450. If I shut it down it will not boot, however after disassembly it boots once, after that another go round to get a boot:-)
