It is time to replace my Precision 7720, but...

I need a new computer. My Precision 7720 is getting a little long in the tooth. 

I just spent two days getting a small recording studio back on line after Microsoft's January update broke their digital audio recording gear. The fix for that disaster busted the Thunderbolt ports which killed of the MADI inputs. 

We finally broke down and tried Linux Mint and low and behold, everything is back. It took some tweaking, googling, and there is a finely woven tapestry of obscenities hanging over that studio even now. But it works.

I can no longer trust Microsoft. So I'm having to make a lot of changes. 

But the problem is your telephone sales staff will not sell me the computer I want without Windows 11 installed on it. The Dell Linux computers I have been able to find on your web site are all kind of anemic for my purposes. 

My question: Is there a way to get the computer I want preferably with Linux on it or sans OS? 

If you can't do that, it's a shame, but it is your company and you have your reasons. But I will have to look elsewhere for the new machine.
