Mountain bike sizing? - Cycling Mob: Road Cycling, Mountain Biking and More

I would like a 19" mountain bike, but found a nice one that's a 17 for a good deal. Any reason I shouldn't get and just jack up the seat to fit me? I plan on doing mostly mountain bike trails and some xc.
-I'm 6'
-inseam is almost exactly 3' (35" to be precise)
-talking about a hardtail, although if you someone could offer an explanation for what would be different between sizing of this and a fs I would appreciate that as well.

Thanks
I also weigh about 160 if that matters at all
