DIY Enigma 2 receiver

Hi everyone.... New to the club, don't know how crazy my question may sound but, can I build my own Enigma 2 receiver?? Like from A to Z ? What are the hardware requirements? Where can I buy a dvb-s2x tuner ? ( I looked at Alibaba with no luck .. with the system being open source I see no logic on why one can't build his own E2 receiver even a combo one with android included ... So, if it's possible show me where t start 😃
