I would not buy that projector or recommend it over the W1070 due to the color wheel and post-calibration brightness not surpassing the W1070.
You didn't say how deep your room was, or how tall it was.
Projectors have offset, and you must mount them above the top of the screen or below the bottom of the screen. If mounted above the top of the screen, the projector MUST BE UPSIDE DOWN with the models we are looking at here.

With a 110" diagonal the Optoma must be between 12' and 14'4" from LENS TO SCREEN and the center of the lens must be 9" above the top of the screen.
With a 110" diagonal must be between 9'2" and 12' lens to screen. The W1070 has a bit of lens shift, so the center of the lens must be between about 2" and 5" above the top of the screen.
So, if you wall is 13' from wall to wall, then you should be pretty doable with either model.
The screen is a fine entry level model. I might bump up to 120" diagonal, but whatever.
The HDMI cable should only be used if you aren't putting it behind drywall. I'm guessing you aren't. The Redmere cables are nice, but use active electronics to make them work, and as you can imagine, over time, electronics can, and do, fail.
