If it has casters,your all set...Smaller cabs just dont sound as good as full size cabinets(I'm talking the difference between an MG or cheapo Crate/hartke 4x12 cab next to a full size 4x12,not a 2x12).

I was playing a 5150II through one of those new 'smaller' hartke cabs and it was horrid...no punch,no low end,just a brittle,muddy,muffled crap sound...yuck!Just get some big heavey duty casters from home depot and get a full size cabinet...the sound is worth it.
