Ignacio,
"Hannspree" and "Hanns.G" seem to be one and the same - however, my particular models are NOT 'current' models. I beieve that BOTH have been superceded at least one, if not two, years ago.
And, my setup did not happen 'overnight'. I spent many, many years with no desktop PC at all, relying instead on a series of notebook and laptop PCs instead. Then, as I started to use PI more and more, I realised that I needed a machine that would do the Power of PI some justice - so I purchased a Quad-core machine with Vista64 and 4Gb RAM and 2x320GB HDD. An excellent decision, and it meant that I was able to convince myself to invest the €350 in the 28" monitor at the same time (the whole package came to €1250, two years ago now).
As time went on, because I had chosen a desktop instead of a notebook, I was able to upgrade - hence the two auxiliary monitors (at €100 each, brand new!!) and a further upgrade to 8GB RAM, and the addition of two internal 1TB drives, in RAID mode, to complement the (now failed) external NAS 1TB RAID array.
Now, with the power of my desktop machine, I find that I am just making a TeamViewer 'Remote Desktop' connection to the main machine from a far less capable notebook whenever I need to be 'portable' - making my life MUCH simpler!
