Cooltek RM1 @ techPowerUp
 

The Jonsbo RM1 powered by Cooltek turns some serious heads by being extremely compact and lightweight, but with the ability to swallow a fully sized ATX board. On top of that, it comes with a 5.25" drive bay and small fan controller. All this while using an all-aluminum construction.
