Here we go, the small box based on Dual Core Atom 330 with total consumption around 50W replacing a 150W old Pentium 4 tower. It used to be around 35C in my wardrobe, now we are back to silent operation and normal room temperature. As I mentioned before, I have there 1TB 3.5” drive mostly idle 95% of the time and 500GB 2.5” laptop hard drive for 24*7 torrents.
And I am using W7 x64 build 7100 (RC) with it. I tried Home Server 2008 R2, Ubuntu 904, FreeNAS. I believe that W7 beta is so far the best value proposition, as it is very stable, versatile and free till the June, 2010.
