Overview From February 2021 to September 2022, I built and operated a cryptocurrency mining rig using repurposed computer components. The rig was housed in a server rack and powered by five NVIDIA GTX 1660 graphics cards. I used NiceHash to sell the rig’s mining computing power, generating approximately NZ$80 per week during profitable periods. The project recovered its initial costs before Ethereum transitioned from Proof of Work to Proof of Stake in September 2022. ...
Overview In 2020, I started a PC building and resale business, combining my interest in computer hardware with entrepreneurship. Over the period I operated I built over 100 PCs, never received a negative review and generated more than NZ$25,000 in revenue. What I Did Sourced new and second-hand PC components. Built, configured, and tested desktop computers. Diagnosed and resolved hardware and software issues. Managed component purchasing, pricing, and sales. Communicated directly with customers throughout the sales process. Reused components where possible to reduce costs and electronic waste. Key Takeaways Running this business helped me develop practical technical skills alongside an understanding of pricing, cost management, and customer service. It also gave me experience independently managing a business from sourcing components through to completing sales.
