HH (Hi Hagen)
I have a Zalman 160XT (Rev. 1 I think) and it is lots of work getting this to run with linux. The problem is not the LCD, this works out of the box. Touchscreen is a little bit of manual work, but can be done. But you have 5x Chassis Fan in there that need to be controlled by 2 USB temperature devices. So you need a driver for the usb-temp-devices and a script that manages the fan level. Leaving the fans at level 100 is not option as ... well, I think it is clear. I installed LinunxMCE last sunday so i am getting to this point, but my next case would not be Zalman 160XT for a linux setup.
Hope this helps...
