Solved! Safe to order costumized laptop

Dec 26, 2018
I am planning to buy a budget gaming laptop. I have eyed Acer nitro 5 i5 8300H gtx 1050ti. Now this is being sold by a thrid party seller on Amazon. A 128gb ssd is default though I need to select Ram, HDD, and another ssd if like to upgrade. So is it safe to get a customized laptop. Does this void warranty?
