To get to the bottom of this you really need to pull the carpet out. The backing is about 2" thick foam. This absorbs and retains water. You might think it is coming from the front but I could be anywhere.
To pull the carpet the seats and centre console need to come out but once you have a bare tub you can dust it with talcum powder and then follow the tracks to where the leak is. This also gives you the chance to get the carpet dry. You won't otherwise. Even leaving the roof down it will stay damp. Trust me on this.
Tracing water leaks is tough. The Boxster isn't designed well to keep the rain out but if you take your time and trace and seal the leaks you will get this.
