As noted, nominal 20X20" footprint, but actually a little bit less. I presently have mine sitting on a steel tool cabinet (100mm tall, by 480mm wide and 500mm deep, six drawer, and the Nomad is smaller) on a well used Workmate 2 (older Stanley workmate). The tool cabinet is made for (surprisingly enough, as it took me about two years to find this out) holding endmills in standard boxes.
The thing I would look to is a place for dust and chip collection. Lots of options (search the archive). I use a bucket vac that fits under the workmate. I put a fines filter on the outlet when cutting composites and some wood, or other friable materials. I don’t bother with the fines filter when cutting most plastics or aluminum.
Lots of options, but soon enough (when I deal with the base for my lathe) the Nomad will be moving to the top of a heavy rollaway tool cabinet (1200mm long, 500mm deep) to free u some floor space. You might consider a smaller tool chest ( if you are in the US, there is a 22"X26" available from arbor freight, and similar from home depot or lowes) so you have storage and mobility. I am sure similar is available elsewhere in the world as well.
