I have a Zalman HD160 case and was able to use the software and drivers here:
http://www.irtrans.de/de/download/windows.phpWorks fine, though there are some issues:
1) if you run 8gb of ram, then you will see bluescreens on boot. I had to drop down to 4gb, then use the latest drivers from FTDI instead of the standard irtrans usb drivers. That seems to have fixed the issue.
2) on Win 7 RC your skip forward and back buttons will not function by default. Remapping them to ctrlf and ctrlb seems to do the trick
3) inputting show names is screwed up. If I want to search for something, when I hit "2" repeatedly I will get "2abc"
