I have no idea what the take rate for the various options on the early Porsche Boxsters were, but the interior and especially the center console had kind of a myriad of layout variations.
So the basic setup is 4 single-din slots. Some combinations of these precludes (I think) the full width central air vents, so there are two different vent shapes. There are
at least 7 (there might be more, I haven't researched it) interior colors possible and the center console could either match that color, be black, or be silver (I think there actually might be some other combinations, like black and silver in an otherwise colored interior). The vents themselves could be black, interior color matched, and there was even a stupid rare option to have the vent blades wrapped in leather (if you went really crazy, you could wrap nearly every interior object in leather). In terms of equipment...
Climate Control - As with the other single-din items, the locations is dependent on what other options were selected (maybe?), so I've seen the climate control unit in, I think, every slot available
-Manual
-Automatic
Stereo
-Tape Deck
-CD Player (I think there were 2 different versions, one with a removable face plate and one with a fixed face plate)
-Combination sat nav (the only double din piece I think ever offered in a 986 Boxster)
Random other Single DIN stuff
-Cubby (I've seen a maximum of 2, I wonder if you could have optioned 3 without a stereo?)
-Cup holders (2 variations)
-CD holders
-Tape holders (I think these are exceedingly rare)
To compound the permutations even further, at least some models (perhaps only the 550 Anniversary) could be optioned without the lower part of the console, ala GT3. All in all, the 986 probably had something like a million different possible interior combinations. Here's a few:
Tan leather, black console, full-width vents, climate control at top, cubby below, CD player at lower console, cubby below that (gauge cluster rings too! Nice!)
Almost the same but with the double cubbies in the lower console (Why did Porsche offer this level of in the weeds customization, I will never understand)
Crazy as it sounds, I've seen references (in OEM Porsche parts information) to wood interior trim for these cars. I'm not sure if this is OEM or not, but this looks hella bad. Full width vents, black interior, wood trim, silver trim, climate control at top, tape deck below, tape storage below that, and a cubby. Gross.
All black, CD player and auto climate control. Cubby at bottom.
550 Anniversary. Chocolate brown, silver outside trim, half-width vents with cupholders below them, auto climate control on top of CD deck, no lower console at all. This one has
polished gauge cluster rings (as opposed to the brushed ones in the example above) (I really want to get my hands on one of those silver center central sill plates, they look dope.)
Blue, blue outside trim, half-width vents, cupholders, climate control, cd player, cd storage, cubby
Crazy rare double-din NAV system. Ugly half-width vents, cupholders, cd storage, and climate control way at the bottom
So rare I've see few pictures of it, but the manual climate control plate, shown here with the CD player, CD storage, and cubby.
A highly optioned green interior (actually I think this is a 996, but it was available in the 986 too)
My center console happens to be, IMO, a good one. Red leather interior, black center console with full-width vents, cubby, CD holders.
(My OEM stereo kept giving me fits so I replaced it with this OEM-looking Continental)
