Doesn't (or at least, didn't) ASUS make a series of DIY notebooks, w/various graphics card options?
Hmm... Little searching:
"A barebone is basically a
naked notebook sold with only a few main components, allowing the end-user to select and install parts of their choice. A typical barebone notebook is composed of a motherboard, graphics processing unit (GPU), LCD panel, speakers, touchpad, keyboard, connectivity ports, and of course the chassis.
There are several barebones manufacturers, including:
•Asus
•MSI
•ECS
These companies offer barebones equipped with the components mentioned above while allowing users to choose their own hard disk, Mini PCI Wireless LAN card, processor, memory, and optical drive for you to install or choose on your own. While you can't swap out or install the LCD panel on your own yet, barebones manufacturers offer models with various LCD panel sizes and resolutions for you to choose from.
Although barebones do not offer the full upgradeability and flexibility of desktops, it is slowly but surely moving in that direction."
