As replied above, glue and clamps. If the board will be seen (and not carpeted), i would recommend not using screws. They look like hell on an non-carpeted enclosure. Just lay a lot of glue, lay the boards square to each other, and clamp the hell out of it. Then, just clean up then ends with some sandpaper.
