I put together a quick guide for those who may be new trying to enter mining. I did not include GPUs as that can be a challenge but put together a guide that can get a newbie started for everything they need minus the cards for under $500 USD. Depending on the route you go possibly under $400. Also included some starting points for prices that I would consider reasonable in today's market for GPUs. The thing that kills many new miners is thinking paying over $1000 for a 1080ti is okay. Most of the veterans know all this info but hopefully, this can help someone who is new to mining and may find this post through a search.
