Differences between thos 2 nec 3500?

i was trying to buy a NEC 3500 on newegg.com but they have different kinds:
the 3500A and the 3500AS

what’s the difference?
which one is better?


There is only one ND-3500A The faceplate or included pieces may differ.

S= silver. The drives are the same other than color.

oops, ok, makes sense now.

now, which oone would be better (pricewise) knowing that i live in california (gotta pay taxes)? the one for $64 with free shipping or the one for $61 with $4 shipping?
i still gotta pay taxes on the one i choose.

With only a dollar difference go with the color you like.
