I'm going to post the same answer here, that I sent via our sales email,
I don't have a solid answer right now, we are planning on testing it out, since one of us has a Harmony remote at home but I don't think we will get to that today, but seeing as most of the Harmony remotes seem to be able to control Media center devices (Ie Xbox 360) setting the remote to use those codes SHOULD work with the GX.
If your purchase one from our website, the option is "UPS Express Saver" for our fastest delivery.
The GX requires a single bay, a USB connection, a Windows OS, and LCDStudio software. LCDStudio will pull info from your system and various monitoring apps and show it on the GX as part of your custom playlist.
The two shipping options I see on my account are UPS Saver and FedEx Priority. If you make an account on our .com site and check out with a GX in your cart you'll be able to see the options available to you.
Sorry for the delay, it seems the GX bracket is difficult to describe. On paper, it's black aluminum, there are no brushing effects, and the finish is rather matte. If you haven't already, you can check out some of the builds in our gallery to get an idea of what that means visually.
