Yes because:

1. Apple first failed to update the cheese grater line for years consecutively

2. Then Apple's redesign of the Mac Pro transformed it into a larger Mac Mini trashcan which wasn't really expandable compared to the original cheese grater line. No one asked for that.

There is evidence for demand for a reasonably priced Mac Pro Tower if you look at the Hackintosh community and eBay sales of older cheese grater Mac Pros, but Apple keeps refusing to meet demand.

The cheese grater was already pro, not consumer. The last consumer tower was probably the G4 era, afterwards the iMac, mini, and laptops took over consumer completely, leaving towers to the pro market.

There is "niche" demand for consumer towers, sure, but I don't think it would be worth Apple's effort. The iMac 5K is really good, and its even the cheapest option to get one of the best displays out there.

Yes the cheese grater was Pro and it was at a reasonable price starting at $2k- 3k depending on the model. Yes that’s adjusted for inflation.

$2400 in 2006 is just over $3k in 2019. Not sure if that is consumer, more like a higher end iMac sans display.

Yeah, you're paraphrasing what I wrote. It is not consumer. It was called a Mac Pro and it's half the cost of the new Mac Pro, accounting for inflation
