Unpack the tools you know that you'll need and set them up in your temporary work area. Spend 10 mins getting set up. Get the systainers out of there, if you can, or stack them up in a corner/adjacent room. Getting tools out of, and putting back into, systainers is a pathway to frustration. If you can, try not to work on the floor - some kind of temporary bench, maybe making use of those now empty systainers.
It's always better to 'look at it, rather than look for it'.
