01. Introduction

So Hardware, well what to buy is the question of course ? How much does it cost to go open source at home ? Is it expensive ? That is a question that will forever be answered differently depending on what hardware is available in the market and if our needs change over time. 

Regardless, we can distinguish Hardware in two main categories namely DIY and Already assembled Hardware. The DIY is pretty self explanatory but the already assembled hardware comes often at a cost.
