That machine there does look very interesting, but I am not sure about it for a NASlite device.
It appears to have limited storage, with I believe only 1 2.5 inch drive. The one nice thing is that it is so small. Considerable smaller than the mini-itx standard.
For a network attach storage I feel a better solution is needed. Maybe you only need 1 100gb or less server than this system may appeal to you, but I feel there are better solutions out there. I did not see a price on the site but there are probably more financially friendly devices.
I would have to venture a guess that you would be atleast $250 maybe nearer to $300 for that machine plus a 100gb drive.
I know the machine can double as a computer but if it always running naslite than I feel the following product maybe a better deal financially.

Thank you for that link though as I feel this computer would be well suited for thin client use.
