Any one else care to chime in on the box? Or at least agree with the model #? How about some input on straightening the metal on the sides where I cant get a hammer inside the box? Finally any input on how to repair the sagging drawers would be appreciated/.

What else are you looking for? Don't believe me on the model number?

If it is a canada made box, they used goofy model numbers. USA it would correspond to a KRA58. Just look on the back it is stamped on there, it may be light but it is there. That is the only way you will know for sure the model number. Does it measure something like 26"Longx12"Deepx14.5"Tall?
Best advice I can say is to work slowly and think about how the hammer impacts are going to effect the entire structure. If you don't have proper body hammers, wrap a standard hammer in duct tape to avoid excessive marks. Use wood as a back up anvil or dolly.
Fixing the dents on the sides is going to be a challenge without really getting serious. As you have found out the double wall limits your access to the back side. You could use a stud welder, weld a stud, pull on the to remove dent. Same caution applies with the standard hammer when applying forces to not further harm the box.
Measure the diagonals of a square when trying to get the box square. Ideally they should be equal. Ex. the front opening, top, lid. Keep measuring and try to get everything symmetrical, and square. This is probably the best tip I can offer.
The middle supports for the little drawers are probably going to be the most pain. Really they should be removed straightened and re welded. However their alignment it pretty critical. They need to be parallel to the sides of the box otherwise the drawer will bind are they will be tapered. Once you get the box square, triple check it, check that the drawers do not bind and then weld up all the cracks.
That ***** the box has so many issues. From the original pics you posted it didn't look nearly that bad.
Did you pick up that side box as well? That looked like a super deal.
