The screen is just a VFD in the original OEM case, and a poor one at that. Just simple text display, no touch screen that I ever saw on those cases. That's not to say they could not add one, but who wants to get up off the couch to go touch a touchscreen on an HTPC when it comes with a remote. The stock case is well known for its' shoddy IR remote. C-USA's solution may be a bit more elegant, I suppose.
So what is the deal here? Is it a workstation or a HTPC, lol. Selling $25,000 graphics workstations crammed with PCIe SSD's and Quadro's is one thing, but the HTPC market is a completely different beast where you're not only going against the other HTPC makers, but also against things like Slingbox, Roku, Boxee, AppleTV - and to some extent even the consoles, which can all run Netflix just fine.
