LED Strip project

Hey, ive decided to use led strips inside my pc case alongside a custom side window.
My brother adviced me to use arduino for the project since theres alot of options using it.
Ive found this arduino and decided it will fit my purpose
Ive got several questions, firstly, what led strip should i use? i want full rgb but i had trouble finding what i need to use, are strips like this good for full color? or are they limited in their possible color.
also can someone give me an advice about how to connect the arduino power supply and led strips together? (i have a soldering iron)

Most strips are 12V. There are regular common cathode strips and WS2812 addressable strips. The addressable strips have the advantage of being able to control each led individually. There are tons of tutorials online.
