Well easy is a relative term. You'll want to use a flare nut wrench on the lines and have the ability to bleed the brakes. The only other thing for me was that my MC was frozen to the booster and took about 40min of wrangling to free it. Don't forget to pick up some bench bleeding supplies (barbs and tubes) if your new MC doesn't come with one.
If you're taking the booster out to clean it up, it's a pretty tight fit. You'll most likely need to be able to bleed the ABS or take it to someone after who can do it. Perhaps it's possible to get it out without removing some of the ABS hard lines, but I couldn't.
