Any of them will really work for you, honestly. Unless you want something fancy that changes colours with a remote or anything, just get ones that are the right size you want, etc. Are you just trying to light it up a bit and have them on all the time?
I know Corsair has some expensive stuff you can control with software. Actually my case came with it for the fans, however I ended up just leaving it White or something. I don't really notice it much since it sits under my desk.
