PCs that are cooler, smaller and faster were announced by computer makers Sunday in advance of Computex, with the new machines featuring Intel's speedier fourth-generation Core processors code-named Haswell. Asus, Cyberpower, and MicroCenter announced all-in-ones, gaming laptops, and desktops with Haswell, with major PC makers like Dell, Acer, and others expected to follow in the coming days. Many new PCs will be on display at the Computex trade show in Taipei, which opens Tuesday.
