So just to clarify a "Receiver/Drier" is the same as the "Fluid tank", which also known as a "Dessicator"?

"Receiver/Drier" = "Dessicator" = "Dehydrator"

The receiver drier is a metal can containing an desiccant.
The drier is located between the condenser outlet and the TEV inlet.
A desiccant is a hygroscopic substance used as a drying agent.
The drier does 3 things: holds liquid refrigerant, absorbs moisture, helps
to remove minor debris (not in design but it does help to trap debris depending
upon the location of the desiccant package and flow design inside).
A receiver drier is used with systems utilizing an expansion valve (aka TEV, TXV, TX valve).
An accumulator is is alike a receiver drier however it is utilized in systems having a orifice tube.
Your system has an expansion valve.

The drier's location in the system is below.

Get yourself a new condenser, drier and the 4 orings.
Have them installed by a mechanic whom is familiar with the Boxster,
and whom has professional AC equipment.
Then, drive the car an enjoy it.

Thanks, that is my plan. It is located and accessed in the frunk by the battery correct?

Grab yourself a copy of the shop manual online, lots of sources, probably section 87 for the AC. They will be calling it a 'fluid tank'. Here, we call it a drier.

Years ago, with R-12 systems we used to take the drier out, put it on a baking pan, in the oven at 200 for about 3 hours. Then, take out, and quickly take it over to the car, install, and pump down for 30 min. Seemed to work great on the older stuff, guessing it would still work on an R-134 system.

We were a lot cheaper back then, but we still wanted AC!

Attempting to dry out the desiccant in a receiver drier that has had refrigerant oil in it is difficult because the oil entraps the desiccant. To know if the process works 'scientifically' you'd have to perform the science.... dissect the canister, attempt to weigh the desiccant and determine if the mass is less than dry fresh desiccant, again very difficult to do with oil soak desiccant.

More often the baking to dry process is used on desiccant that is not soaked in oil.

Considering the cost of a new drier why play with the issue.
