In looking at built-in grill shells I'm wondering if
anyone can point out to me the flaws in possibly using
a normal standalone grill, but using that instead as a built
in grill. Take a really nice all aluminum unit with two
front doors, don't attach the wings or side burner or wheels, whatever,
to it, and instead built a nice rock/brick/tile counter around it.

Based on the price difference between what look like to me
similar quality built-in vs stand alone grills, it looks like it
might work. You'd need to get the right grill, but it might work.
And you might save like $500 or more.

Anyway, can someone poke holes in this idea?

Thanks,

Carl

No... Plus with a roll away you can acutally move it to a convient spot
and power wash/clean is without making a complete mess out of your
patio/kitchen hard features.
