now settled - took a while though - probably due to low performance of my cheap PC !
This box - seems they down in China made a decent job of it !
I surely appreciate fully the Long life guarantee in the form of this inbuilt ventilator - which I feel is in NO WAY too noisy.
Data images take a couple of minutes longer here as compared with my SR1 box linked to my decently performing HP Notebook.
Hope this may be of use to some of you.
