Hi [NAME]  can only comment on Dell refurbished XPS 15 9510 laptop. If purchased from Dell outlet, refurbished and original systems get the first year Dell warranty. Dell provides the first 21 days Approval so that user can check that refurbished system is as advertised with no faults. Dell Refund policy, New vs Refurbished - Dell Community Please check invoice to see what Dell has stated about returning damaged refurbished systems, you may have been given first 30 days Approval, etc. because there is a very small difference between original and refurbished price.  As soon as possible, please use your Dell login to open your online Dell account (in top RH corner of XPS 15 9510 webpage).

Not sure what Newegg's Gamers Nexus motherboard is or if it has Dell warranty, as this information was not provided. 
A few days ago Newegg send Gamers Nexus a refurbished motherboard which is actually used by Newegg, this motherboard pin was bent, When NewEgg buy this refurbished motherboard, they does not open the box and they do not need it, so it was sent back to Newegg for a full refund. Now, Newegg claims that Gamers Nexus bent the CPU pin, even though they never open the box, so they decline the refund. Newegg used it and bent the cpu pin, but they put blame on Gamers Nexus. Gamers Nexus research and find that Newegg actually cheated with them.
