To keep it simple you have to:
Remove the speedster humps
Install spinocks on each side
Then buy a hardtop
I paid $900 and I was lucky enough that was the same color. If you have a weird (rare) color then you will have to pay to get it painted (about $300) Most people want $2000 for a used top but they normally sell for $800-$1400.
I got a hardtop and trust me it the best thing you can but for the boxster. you can remove it for fun trips on curvy roads in about 5min. and put it back on for the day to day freeway commute. The noise differeence between the softtop and hardtop is amazing!
