This subject was covered before I think, there were some nice ideas on how to carry 2kxl and not break it.
It depends on your creative mind only

You can figure it out in the store, just take mpc's dimensions and check some backpacks or travel bags. Don't forget to reserve some space for additional cover such as wide and thick sponge on the top or something like that.
Personally I had to carry this machine once, from one country to another and I used everything that was necessary to protect it. Some bubble wrap (actually it was a huge amount of it

) and a simple cardboard.
So, if it's just for one time travelling, you can figure out something temporary.
Take care and keep your new machine safe
Congrats on new purchase by the way !
