Since I got a few pm's and i see a lot of people asking how to do it, here is one that lists most of the ways to do it (if not all)
there are a few ways to find out your box number:
method one
open your terminal/command screen
type in: 'ping yourusername.110mb.com' WITHOUT WWW.!!!
wait for a while and an ip should appear (answer from x.x.x.x)
195.242.99.89 is box4
195.242.99.184 is box5
195.242.99.208 is box9
195.242.99.192 is box10
195.242.99.215 is box11
195.242.99.91 is box 12
64.191.15.150 is box 13
66.197.252.182 is box 14
now you know on which box it is

method 2:
method 3:
after logging in it will say your box number on your 110mbpanel home, under the section ' General Server Info: ' (e.g. This Account is On Server/Box : 5)
EDIT: Sorry, please move this to howto section, i was sure i was there already but i must have mis-clicked the sections. sorry again!
