It's just a board of metal with hundreds of holes in it. But it's way more than this. It's LEGO for grown ups, meccano for nerds. I never had so much fun and pleasure building a board. Everything fits so easily, MODs of course, but cabling is a kid's play. Cable ties can be put anywhere, tidy cabling, all over, screws, bolts, nuts, what have you... it's superb. It's light, it's solid and well finished and well designed. The reddish/orange accents are a delight for the eye. The little removable metal plates on the sides makes for a very modular and exciting experience. I love it.
