first AW is also a Dell first.  It is called Area 51 Phobos.  Not ALX, just a case with AW power supply.  Managed to put another Dell X58 motherboard inside and get it going.  It was a thrill to see the LED light work the first time, but now I am not impressed with the curvy outline of case using way too much plastic shell skin.  Its hinged door is also a bad design.
