TweakTown posted a review on the NZXT Sentry 2 Single-bay Touch Screen LCD Fan Controller

So, the logical progression was to reduce the size down to a single bay, but how do you maintain the same functionality as the LX without the use of buttons? - Simple conductive membranes which switch on contact provides a cheap and effective touch screen solution.
