Hey,
I just did this upgrade today for my Clevo P370SM-A , bought a LP173WF2 (TP)(A1) glossy panel from ebay, total was 80€ shipped to Finland. Its from a Dell Alienware m17x R4 machine disassembled, in a mint condition. Dell product number is 0C30PY.
eDP cable i bought from CEG, ebay, LG 3D EDP CABLE, 6-43-P1701-010-JD. Its from a Clevo P170HM3 machine. It was too long for P370SM-A, but the connectors are the same. Managed to fold the extra long cable under the palmrest ok. 30€ + shipping
Works like a charm, have to say its worth it, so much better display with 120hz than the original panel.
There's a film about this upgrade for P377SM-A, screws were almost the same in P370SM-A, can use it for help.
