Mackintosh store?

Hey guys! I’m noob with hackintosh and computers, so i decided to buy a ready one.

I found some stores who sell mackintosh ready to use and some of them give me guarantees, which is awesome for me.

I want to ask if anyone has experience with that or another stores that i can try.

I found theses ones:

iclons.com macstorm.eu xdscomputer.co.uk

thanks :)
