The X-01 Power Armor suit is the best, most powerful set of Power Armor in Fallout 4. 

This page guides you on how to easily get your very own suit of X-01.

You can find a complete X-01 suit close to the Custom House Tower (bottom right mark on the picture above). There are Gunners, Raiders and even Super Mutants around, sometimes fighting among them. Be warned, it's very well guarded, so bring your best weapons and armor.

Head into the 35 Court building at the location above. There are 2 laser turrets just above the door leading in. 

Enter the lobby and immediately head left up the elevator. 

At the top of the elevator, take a right up this winding passage. You'll be attacked soon after reaching the top, so prepare some high-powered weaponry and any buffs you might want equipped. 

After reaching the rooftop plaza, a pair of doors will open revealing an Assaultron and a Sentry Bot. There's very little space on the roof to maneuver, so it may be helpful to expend some high-powered ordinance and clear them out quickly. You can also funnel the Sentry Bot going back the way leading to the roof, and deal with the Assaultron first. Pulse mine or pulse grenade helps here.

Once the two bots are down, enter one of the two newly opened rooms. 

Press the red button. 

Now enter the second open room and repeat. 

The center door will open, revealing a pristine suit of X-01.

Grab the suit and celebrate the fruits of victory.
