Hello,

I am using a 10.6 inch panel, and the standard triplet. My case is 12"x22"x9". What size FS mirror do I need?

I was thinking of this one.. would it work?

It depends on where you are placing the mirror (the further from the LCD, the smaller it needs to be, but some have reported that image degrades the further from LCD the mirror is placed. Others, including me, have placed the mirror at some distance with fine results.).

There are several ways for determining size needed. I mention one of them here and SupraGuy describes another one here.

Well I was thinking between 3 and 4 inches away...

Damn does this mean my image is going to suck now that I used a folded design? My box is already built! Is there a way to get an image quality as good as a non-folded design? How much image quality loss are we talking here?

Don't stress over it. You'll take a brightness hit which some have quantified as unacceptable but really you shouldn't stress over it. Your image won't suck.
