How likely will I receive my computer on the expected delivery date if the build is not even complete one day beforehand?

I ordered a customized Dell computer around 3 weeks ago (on Apr 22, 2025). My expected delivery date for the order is tomorrow (May 12, 2025). However, when I look at the order status it says that the build is not even complete. Here's a screenshot.

How likely will I receive my order tomorrow if the build is not even complete one day beforehand? And today is a Sunday. Will they work on Sunday to finish the build and ship it tonight? Or am I more than likely looking at a delayed shipment?
