Clevo, a Taiwan-based ODM (Original Design Manufacturer), is a supplier for other PC seller, including the famous Alienware, Sager, MALIBAL, and even the UK-based Rock PC. Those companies then re-branded the product under their own name and sell it. The latest laptop from Clevo, M590KE, is one of them. This 20.1-inch widescreen gaming machine is going to be retailed as Rock PC’s Xtreme SL Pro, Widow PC’s String 919, and probably Sager’s NP 5960V as well.
