Make your own laptop using Mini-ITX components

Source: Engadget
The main appeal of laptops tends not to be their upgradability: that's what desktops are for, right? Well, if the recent trend for "deskbooks" is anything to go by, then that assessment isn't true anymore. Entering the same league as commercial 19- and 20-inch desktop replacements, and tipping the performance vs. portability scale heavily towards the "need two people to carry it" category is Torquil Harkness' "ITX-Laptop," a computer designed around Mini-ITX components so that it simultaneously maintains a modicum of portability alongside full upgradability. Torquil admits that the end result could have been far smaller had he used Nano-ITX -- or Pico-ITX -- components, but in order to make it "as powerful as a regular desktop" he decided to go for larger parts. Despite Torquil's statement that performance was the aim, we'd have to say on first glance at the specs -- 2GHz, 1GB RAM, and a PCI-based ATI Radeon 9200 graphics card -- that some degree of compromise took place. Still, we believe him when he claims that he "could slot in a motherboard with PCI Express in the future" because this thing's wide open for future upgrades, and that's the point. Never mind the limited specs or the questionable chrome paint job: just lean forward, take a closer look at those computer guts and think "I can do that too." That's the way to stick it to the man.
