Notes
1. There is a price premium on intel's lga 1151 socket due to the newness; if that is optional, then we may save around 5 k by choosing lga 1150 cpu, ram and mobo
2. I recommend genuine software, particularly the operating system software, not included in the build
3. a ups and a suitable furniture compliments the build immensely, not included in the build
4. prices are approximate; also
5. I recommend shopping in stores rather than online due to shipping damages, originality, warranty, returns and related issues
