Neosd team made the right choice, a lots of people here do not imagine the price of a mold, I find already fine that they have decided to make a shell, many others would stay at the pcb.
Now, assuming they had the budget for only one mold
, It was necessary to choose between the mvs or the aes and the most logical choice was the aes for many reason:
1: mvs cartridge can be find at low prices , generally less than the aes
2: mvs are easily openable with screws, the aes are clipped and therefore does not offer easy access to the pcb
3: AES cart being smaller can fit into the mvs, not the reverse.
If you are not happy with your shell, buy on ebay a cheap mvs and took his shell : the one on the picture cost me about 25 euros shipping included.
