Porsche dealership says it's *MOST LIKELY* the brake booster leaking onto the master cylinder and they want $2,300 to fix it which sounds insanely high because I went onto youtube and found THIS VIDEO where the guy made replacing those parts look fairly simple.

I'm wondering if I should try this myself or take my car somewhere else, but I'm worried about the dealership's diagnosis because they said they weren't completely sure until they dove into it. I'd hate to replace these parts and have the problem persist.

You need to diagnose what is wrong first not just replace everything and certainly this is an easy do it yourself with basic tools and not a $2300 job. A very hard brake pedal, works at first and then gets hard, is often a problem with the booster and not the master cylinder. It is possible that it is just the check valve since you have brakes at first. Never messed with the booster on the Boxster so I don't know where it is but I am sure someone here does.
