Thank you all for the infos!
Projector... I've been considering that, but all things considered, I'll probably do that in a year or so and then probably something like that:
https://www.youtube.com/watch?v=lV7ZN_G9ExgI've been playing with the idea of a VR headset, but IMO I don't like the pic quality of the Oculus Rift, once it moves to 4k then things might be different. There are also other VR headsets out or about to be coming out, but E:D has limited / no support for those (yet - and might not get them in the near future, from what I've read).
Also, because the monitors I have are curved(!), that'll help with the immersion factor, plus I'll remove their case (that's really just for protection) and that way there won't be any borders, which would take away from the immersion factor.
About the stand, I've ordered a Deluxe Triple Monitor Stand Free Standing Supports up to 3 28":

http://smile.amazon.com/gp/product/B00YDAYMIEThat way I'm ready for triple 4k in a year or two and I can just get another one or two or three (though I'll need a new mobo, mine supports only 1 x PCIe-16) and go SLI if needed, performance wise. Also I can go the VR route then - which is very demanding of a graphics card, and the Titan X actually has a technology to help with that ("Context Priority Asynchronous Time Warp") and that tech also supports SLI. So, this setup is, I'd say, future proof for the next 3 or so years.
On top of that I ordered TrackIR pro and I ordered and already received yesterday (Amazon Now FTW!) the Logitech Extreme 3D pro - I was looking at the Thrustmaster HOTAS and Saitek X-55 Rhino, but they seem to have a lot of issues, for that price point at least, so I'll wait until a better-quality product becomes available. I haven't done a lot of combat with the Logitech yet, just some practice flying around and shooting into empty space, but it seems quite accurate and will improve at least the combat aspect of things (though I enjoy all aspects of E:D).
I'll have everything on Monday, once it's set-up I'll take a pic and post it here, but that might take a day or more.
