The closest board game I know to a traditional old-school RPG is the excellent League of Dungeoneers which features all the classic tropes of rolling up characters, rolling for GP, equipping and outfitting characters and so on. It has both overland travel and dungeon-crawling, random events, loads of equipment and loot to find, trade and sell, books of quests, random quest generators. You can basically ditch your GM with this game.
Pure dungeon crawlers I own and enjoy include Dungeons of Doria and Quest for the Lost Pixel. Very different games, but both strong on fun and on generating unpredictable situations each time you play.
More Euro-style would be Dungeon Alliance - where you draft a party, each with their own decks of action cards, and try to defeat a dungeon against a timer. The way the dungeon tiles and enemies work in this one reduce the sense of exploration and surprise at the monsters - in return you get to enjoy unexpected synergies in the action card deck you build.
