We will be doing Zotac's new range of boards as soon as they become available.
I've ordered one from shoptonet.de and they estimate that the product will be ship primo next month. It has been delayed before, so I don't think it's entirely certain.
Yes the Gigabyte board is nice, but I miss passive cooling, 6x sata+1x esata ports combined with the 2x PCIe x1 slots (one x16 length). Not to mention that HDMI output is also a nice addition.
I'm going to use the NM10-DTX as a replacement for a VIA SN18000G in a NAS (samba)/ mediacenter (XBMC) setup running linux (Debian). At the moment I'm using a Nvidia G210 to accelerate video playback (through VDPAU), which enables the computer to playback x264 videos with minimal cpu load.
