~65 pounds for a 410-sized cabinet is not much to me at all. The 212xlt I had was 75 pounds, and it felt lighter than my 56lb 210xst just because of the handle placement and the way it balanced when carrying it. The front side of the 210xst was so heavy that, combined with the poor location of the handles, it rocked forward when carrying it, and you had to fight it more. Plus bending over lower to pick it up made it seem heavier. The 212xlt was easy as you could squat down a bit with your knees, back flat, and just lift it right up. The ul410's I picked up where even easier.
I still say everyone should have a quality collapsible hand truck, and get rid of their cumbersome casters. I can walk my entire rig on my hand truck for several blocks, over curbs and ancient downtown sidewalks, with no issue whatsoever. Bass in a bag over my shoulders, and I have a hand free to talk on the cell phone if I want.
Of course, the Neox 212 I have is much thinner and easier to move in this fashion than all those bulky 410's.

But seriously, I did the same with my 212xlt, which is the same size as the huge 410xlt, and it worked just the same.
The Safco XL collapsible handtruck is the best thing out there IMO. They have larger wheels, a larger base plate, and it collapses to around two inches thick, unlike the bulkier Kart-a-bags, and has a very generous weight limit. They're a bit pricey for this type of hand truck, around $150, but once you see them you'll know why. They're much sturdier and more heavy duty than the $40 cheapo's that are for sale in most retail locations. I had to order mine online. I've moved washers, dryers, and furniture with mine. It's highly recommended.
