I have the older M17x R4 as I still have it, I loved it at first but I soon grew to hate the thing. Heavy, expensive hot mediocre gaming machine.
Replaced it after 3 years and the last two years it was used more as a cheap to run plex server then a gaming machine, where the PS4 was IMO better , now got a dedicated PC gaming rig.
I can 100% say I won't ever buy another one. Mine is on its last legs as everytime I boot it the BIOS fails to load and gets stuck, I have to forcefully reboot it about three or four times and then it decides to boot, so I use sleep mode and just pray when it gets rebooted via Windows updates.
Useless laptop? Yes no. Its got its uses, but its certainly not got uses for what I purchased it for..
