My second ever build - been upgrading off and on for ~3 years.
When I was first choosing parts I wanted to go for a black build with white accents, and I finally realized that white case fans would be a nice accent, however I had no idea by how much the white colors would be off. The case fans are very obviously a colder blue, while my GPU's RGB lighting and the RAM are both more neutral. It's annoying to a certain degree, but I'm not really sure if it's worth the time and effort to change out all four of the case fans for either black or neutral-white fans.
I also have the desire to swap out my motherboard for something more capable, but I'm not sure if it's worth the time or effort of ripping out all my components and almost completely starting over in order to get a slightly faster clock speed on my CPU.
