I would have designed it the same way - Thunderbolt is the future of expansions, not tiny little cards you need to slide inside of the HW. This machine recognizes that - They give you 6 (six!) to play with. Thunderbolt IS PCIe, so it's just as fast.. Why should card makers be constrained in expanding the machine to make peripherals small enough to fit inside? If I want 1 solid foot of Disks for my workstation, then so be it. Wire it in over Thunderbolt, and I'm good to go.
