Zotac is improving their ION line up by offering a high-end ION based Mini-ITX board.
The new board will be dubbed the ITX-F will have the inclusion of a PCI-E x16 slot. It also includes an Atom 330 CPU which should give you enough power to run your Nettop or HTPC. The NVIDIA ION features HDCP outputs through VGA, DVI and HDMI, 802.11n WiFi, Gigabit Lan and two slots for RAM. There is no word on pricing just yet and no mention of any overclocking features that might be hidden in the BIOS but this still looks like it might be an excellent choice for an HTPC.
