HEXUS.net reviews a 5.6KG beast of a desktop replacement system, sporting a 3.6GHz Pentium 4 CPU and two 60GB 7200rpm hard drives. Rock's XtremeTi may not be very portable, but it is powerful. From the review: Thinking of the Xtreme Ti in strict DTR terms, the overall impression is favourable. You can zip around Windows XP, thanks, in main part, to Rock's use of 2 60GB 7,200RPM laptop drives that are pre-configured in RAID0. Browsing around in 2D mode, the machine felt faster than Dell's Inspiron XPS Gen 2, which shipped with a single 100GB 4,200RPM drive. The screen is a hit-and-miss affair. You'll either love the high-contrast 17-inch (1680x1050) screen or immediately dislike just how reflective the X-Glass-equipped panel is. Rock's got most of the performance bases covered, too, with a fast Mobility Radeon X800 (now XT) card providing decent framerates at the laptop's native resolution. There's also plenty of memory and the optical drive is decent enough.
