I don't think you can do HD but you can do component w/ a 5 wire to vga adapter and run composite through your stereo for sound. I can provide a 50ft. 5 wire cable and vga adapter if needed as well.
VGA can do resolutions greater than 1080P, VGA can be used for HD. You will notice no difference between it over HDMI/DVI, or component cables.
Native reso on this projector is 1024 x 768, not quite 720P but it'll give you a great HD picture!

I mean analog, as is, you cannot use a hdmi to vga wire or adapter without a converter box. The thing is I run all hdmi through a switch, how would I connect this?
