It seems that you want white.
I like white as a case color.
It would also bother me that there is no dvd capability, so of the two, The R4 would be my pick.
I suppose, you want quiet also.
If you want small, look at the Silverstone M-ATX PS07W

I came across this case searching for a not so deep case for a friend's build.
We bought the black version, and the case is a well designed gem.
If you can use a M-ATX case, check it out.
