The X-6 cabinet comes apart in 3 pieces. There is one monitor behind the cabinet that bolts on the back, there is the main section, and there is the control panel section. The main section will fit through a standard door, I think my door is 33 inches and it ALMOST didn't fit until I tipped it at a slight angle. I'd recommend a total of 4 guys at least to load and unload the main section into a truck. I can push it around a room myself but loading it the middle is HEAVY. I think the control panel section is just over 24" deep, main section is about 34" or so and the back monitor is another 18-20" off the back.
Good luck on your quest(s) to get an X-6, I love mine I'd say its worth the room. I had to put mine out in the garage where it never gets turned on even but its so cool I wouldn't even think of selling it! For well over a year I had my X-men 6 in the livingroom which was a sweet centerpiece, can't wait until I have a larger place and can have all the huge games without squeezing them.
