When I first approached the ZOTAC NM10-DTX I was reminded of the war of worlds between Intel and NVIDIA. They each had their take on the usage model for the Atom and the netbook/top. At the time Intel and many of their partners claimed the Atom was not meant for gaming, HD video or content creation. They stated flatly that the Atom and its platform were primarily for content consumption and simple productivity work.
With the NM10-DTX WiFi we have seen this proven again. Yes, you can do some minor content manipulation (transcoding, simple video and photo editing), but for the most part you are very limited by the platform's reliance on slower DDR2. We also shied away from dropping in a high-end GPU here as it is not something that anyone in their right mind would ever do. Instead, we dropped in a HD 5450 for our gaming tests only in keeping with the passive cooling model.
In the end we found that the NM10-DTX is a handy little board. At $130 from Newegg.com it is good value, considering you do not need to buy a CPU or GPU (for the most part). But even if you do want to extend the HD resolutions out to 1080p, with a HD 5450 you are only paying another $50-60 and you are on your way.
If you are looking for a small, quiet and flexible system for a kitchen PC, HTPC, or for the kids to use for browsing, then this could be the one for you.
