Hi,
I am in the Uk, and moving house.
t have an HP T5325 Thin client which uses the
same Marvel chipset as the guruplug.

Someone got as far as getting one to net boot plan9 but
didn't (If I remember correctly) get the graphics working.

There is also an SATA interface which can be accessed with
a little soldering.

Free to anyone who wants it - I may ask for a postage
contribution if you are far from me. Be quick or it goes
into the skip.
