RGH Xbox 360

I am interested in getting a RGH Xbox 360 here in the UK, from were i don't know.

What i would like to ask is, will an RGH console play copied disk, not original from any region be it Jap, US or UK to one of these consoles. My second question is will i be able to install these copied disks to the HDD and just run from there. I would also have to make sure the CD drive will be flashed so can this be done with one of these modded RGH machines, to run copied games that is? Thanks for any advise
