I bought that light kit you have listed as the second link but mine was blue. I personally wouldn't think that a blue/purple neon light fan cover would look good with a red UV (no led) fan. Although, for 30 dollars you save quite a bit of money on those parts, I added it up one day and all the pieces included in that set, if bought separately would cost about 60 dollars. So even if there is a part you don't want to use it is still a good deal. As far as the case... kinda skeptical when it comes to cheap PSUs, I try to get a nice PSU so I don't run into problems later on.
