Hello, I wouldn't usually send this out but traffic on the Cube list seems particularly low so ... I finally took the leap and put in a new HD. The upgrade went flawlessly and this being the 2nd time I have ever taken the Cube (Grail) out of its Enclosure (Ark). It took about 3 hours while watching Desperate House Wives and using the optical drives IDE connector to transfer original disk's content. Special thanks go to cubeowner.com (Laurie) and Carbon Copy Cloner (bombich sw). The cube is so silent now that I can't tell if its "doing" anything. Nitty gritty: Seagate 340016A 40GB Absolutely stock 450Mhz Cube with 576MB RAM OS X 10.1.5 Torx T10, T8 screwdrivers Boot time (including many app launches) went from: 2min. 18 sec to less than 2 minutes. Temp: Pretty much the same as before: ThermoInDock says 32*C Cheers, gsteel
