I also have an HB i2ex. Initial setup was fine but as usual, I wanted to poke around with it. The initial kernel was quite old but I now have 3.14.14 running. I will at some point, need to install a mSata SSD for capacity and speed. However, I don't think it will all fit in a standard RPi case with that big red heatsink! At present, I have no serious work for it but that will probably change as I outstrip the capability of the RPi's around my network.
NewIT were quick and responsive delivering the HB and a Cubox-i once supplies had been obtained from Solid-run.
