Help build a new computer

My name is Kaleb, I am attempting to raise money in order to build my own tower computer from the ground up. I am a student at frontrange community college and am taking classes to eventually get my A.A.S. in cybersecurity and cloud Computing. One of those classes is the CompTIA A+ certification in which I will learn about diagnosing and troubleshooting computers. Building my very own personal computer will help to advance my knowledge in this field and give me a computer to practice on so someday I can protect people's information from hackers.
