I would write a custom cms... but then I've always done this. Almost all of my sites are driven by custom cms and I can't say they rank any better or worse than hard coded sites.
Just be very careful with repetition eg title, meta data, content and links. Too much boilerplate style code without a decent volume of changing, unique content will land you in the duplicate content zone.
