General LinuxCNC to servo motor Q

Hi guys,

About to build a 1.5*1m cnc router. I have experience running all manner of other machines, I've built machines, etc, but new to the CNC side of things. Dabbled in programming, robotics, etc

What should I be searching for if I want to use LinuxCNC to run servo motors? I presume I need a way to connect the laptop to the servo motor drivers to handle g-code conversion for the drivers. Powering seems straightforward, 1 supply per driver. Ball screws and linear rails for motion control, etc etc

Also if anyone thinks I shouldn't use LinuxCNC, feel free to tell me why/why not. Servo motors because it is a learning experience before I attempt to fix a ~6m*3m milling/router table with a similar but beefier construction.(Y gantry, cast iron bed etc)

Tl;dr: PC -> ???? -> servo driver -> servo motor. What is the ????

I'd investigate the various hardware solutions provided by Mesa. I think, but have known to be wrong, that a 7i77 maybe a good starting point.
Speaking generally a laptop is not the preferred machine, as many of the built in power saving options can cause latency spikes.
Corporate machines with i5 or i7 are good starting points, they are usually plentiful affordable and are well supported by the Linux kernel.
The only reason not to use Linuxcnc would be if you're not a methodical type of person, one that is not willing to RTFM or believes the insane ideas of Windows users regarding Linux in general.
Hopefully the more knowledgeable Tommy and PCW will chime in and correct any stupid things I've said.
BTW laptops can work, but generally a PC is a more guaranteed path for success.

Good luck

@ X Trench Run Thank you so much 

1. PC -> ethercat -> ethercat servo driver->servo motor
2. PC ->mesa card+breakout board -> servo driver ->servo motor
