So you need bare metal first to do everything. I searched in google for about 3 months and decided to buy a used HP/Dell Server. Some other options were going on budget and getting a NUC, Mini PC from aliexpress etc., Finally decided to purchase used server mainly because i wanted to get the feel of it. Server & Rack: I purchased a used Dell R210II from zaco computers. Came to know about them from some posts i found in quora.
