Actually this is my "own" build - I had decided on the core items of Philosopher Stone, Boots of Speed, and Heart of Gold because he is a tank. Other items just didn't make sense on him. It's no surprise lots of others do the same though because these basically are the best items for him.

I prefer magic penetration marks since that's most of his damage output. As stated though, you can replace these with Attack Speed for slightly faster jungle clearing. However, since Nautilus has horrible base stats, giving him damage or attack speed is very inefficient in my opinion.
