Hey, New PCMR user here, about to upgrade January 2018, specs changing from laptop are:

i5-3210m 2C/4T 3MB 2.5 Ghz -> i7-8700k 12MB 6C/12T 3.7 Ghz (Likely OC to 4.5 Ghz) | Intel HD Graphics 4000 -> ASUS ROG Strix 1080 Ti OC | 4GB DDR3 1600Mhz SODIMM -> Corsair Vengeance RGB 16GB 3600Mhz DDR4 DIMM | 500GB Laptop Toshiba Hard Drive -> 250GB Samsung 960 EVO M.2 SSD + 4TB WD Black Hard Drive | Crappy Broken Dual Band Wi-Fi -> AC Wi-Fi | Random Generic MB -> ASUS ROG Strix Z370-E MB | 15.6" 1366x768 60hz -> 27" 2560x1440 144hz 1ms G-SYNC | Laptop (Frame) -> Corsair 570X RGB | No RGB -> A lot of RGB... Seriously, A lot... 6x HD120 RGB + Corsair Lighting Node Pro | And Finally, Insanely loud laptop fans -> NZXT Kraken X52 RGB |

For full details of my laptop, just search up Lenovo G580

Thanks for reading, stay tuned for my build...
