Just putting this out there before those desktop elitists come with their "laptops suck, they will never be as good as desktops" arguments...
Eurocom offers a series of top-tier notebooks that house full desktop specifications, upgradable Coffee Lake-S CPU's (Yes, even as high as the 8700K), upgradable Nvidia Pascal GPU's (17-inch models sport dual 1070's and dual 1080's), quad ram slots (up to 64 gigs of DDR4 clocked at 3000Mhz), you name it.
They're literal desktop replacements.
