So.... good news.... Even with the 2nd delay notice pushing back to the end of Nov, the system did arrive 13 Nov via FedEx.  There seems to be a big disconnect between the customer service folks and the people that actually build the systems.  The system was shipped the very next day after I was told of the 2nd delay and they didn't seem to have any info on what the build status actually was at any time I inquired about it. Years back they would show the build statuses in detail, not just "In Production"... I miss that.  If you are told they are waiting on a certain part "i.e. Chassis", take that with a grain of salt.. I really don't think the reps have access to those details.  Patience will be the key in getting thru this process.  I was given the choice to accept the delay or have the order cancelled only 1 day before it actually shipped.  So glad I didn't cancel.
Placed my Order back on 30 Sept and still not put into production.  Chat w/ rep states do not have parts (Chassis) however there are several PCs with the same specs the website says ready to ship.   Have several Dell in my household and ordering had always been a good experience... till now.   They don't update the status of your order and leave you will no answers or estimates of when you PC might be built.... let along shipped.  As I started to worry about my order and reading all the other comments on delayed shipments (Most of them laptops being sent from China).  I did not think that desktop chassis shortage would be an issue (Made in Mexico).  I had gotten a good deal at the time of the order nearly a month ago, but starting to wonder when or if I will see this PC.  As others have said.  All the responses seem to be cut and past and although they are nice... they are not helping you get the info you are asking for.  Its just the same, you will receive an EMail when your order ships response.  Very disappointed.  A good deal is not a good deal if you never get the product.
