The Husky tool box you have in mind will be great for storage of all you accessories for the CNC but not good for the actual table to support the CNC.
Drawbacks…
The folding table in the rear will always need to be collapsed before you move the machine around.
The 51 inch height will be way too high for you unless you are 6’9" tall and will be very hard to reach the rear of the machine from the front.
Not all the wheels lock and if you changed the wheels to something that will work you wont be able to get to the wheels under the rear work surface easily.
Here is a comment from another post
Think and plan is the key to setting up any work area. You will need more room (work surface) than you think, plan for your laptop, tools while in use, dust collection and electrical power are just a few.
There are many options out there.
