We've discussed IKEA here in the past and some our our topics have touched on the topic of altering those inexpensive pieces we purchase from our favorite blue and yellow big-box store. Little did I know that there was a blog dedicated to such exploits. Anyway, look closely at the photo on the right and you'll see an IKEA Effectiv cabinet topped by a quartz-slab countertop in this Eichler remodel. Perhaps not quite a "hack" but still I think it looks pretty slick.
As for the other "IKEA Hacks" on the site, it looks like a majority are geared more towards the dorm-crowd (not that there's anything wrong with that) but have a look around, you might just find something useful. Allen wrenches not included. :)
