If you're still on that original factory cap you might want to have the coolant flushed with the factory pink coolant and have the updated cap on hand. The 101 Projects for Your Porsche Boxster book recommends a flush every couple of years, probably great for DIY'er who can vac fill.
In the meantime it's useful to have a small LED flashlight in the armrest storage that you can use to light up the coolant tank from behind so you can quickly see the coolant level. Sometimes it's hard to tell if its too dark or bright out. If the coolant is below the hash mark on the tank you may have a crack/leak somewhere. Once its vac-filled it should not fluctuate unless there is a leak or air has gotten in. I got in the habit of checking this with the flashlight before I got in for a drive around the time my water pump started sounding funny. Sure enough I missed my appointment to have it swapped out due to work, and it let go the day before my new appointment on the drive home... Murphy's law.
