Jetway 780G Mini-ITX
Since the above two motherboards are for LGA775 processor, it is time to look at what fans of AMD can look to buy. The selection is somewhat less attractive for those who choose AMD processors, as most of the boards offered either available from either JetWay or Zotec, and Zotec unfortuantly doesn't offer anything as modern as the GeForce 9300 chipset for AMD processors.
This leaves JetWay, a motherboard manufacturer with a remarkable lack of reputation. If you'd never heard of them before, don't worry - their company is so small that they don't even seem to have a Wikipedia entry. But if the products available through most retailers are any indication, JetWay has a fair amount of experience in Mini-ITX boards. They offer several different Mini-ITX boards based off chipsets for both AMD and Intel processors, and customers seem satisfied with their products.
Their best product is likely their 780G-based Mini-ITX board. When it comes to features, it is essentially bone-stock. But that is fine, because AMD's 780G is a great chipset even in its stock form. This is thanks to the inclusion of Radeon HD3200 integrated graphics processor. This solution is roughly comparable to the GeForce 9300, and should be able to tackle high-def content without trouble so long as it is supported by a dual-core processor. JetWay's 780G Mini-ITX board can even support some Phenom processors, should you have the need to cram a quad-core into this small package.
The only real downside to the JetWay 780G Mini-ITX board is that its price of $159.99 is steep compared to the more feature-rich GeForce 9300 board from Zotec. However, this JetWay board is certainly the best option for AMD-powered Mini-ITX systems.
