Air is an insulator, so if the alu-chasis is not connected with a thermal compound, it does nothing.
It will be warmed up by the hot-air movement, but if it gets warm, the fan is not moving air in an efficient way, so i would ask myself, if my NAS is okay or not.
So if the alu-case gets warmer, you know that the chassis is trapping heat inside.
You have a metal PC case. Touch the top case - if it is warm to the touch, you dont have a good exhaust fan.
If you have a good exhaust fan, the top of the case should be cool to the touch.
Or even simpler test - open your metal/alu PC case - did the temperature drop or not? If yes - you dont have a good air setup, so the warm air builds inside your case. If the temperature is slightly lover, then you have a good air setup in your case, so the difference is just a minor,
If the temperature rises when you open your case, then your fans are very well channelled, and provide a good push-pull configuration, that looses its efficiency when you remove the casing panel.
Anyway, alu-case can be good, if it is a part of the cooling, with thermal pads/compound, like this one:
