You have $1500 in head room if that matters to you, but the point is that you have that choice if it does.

What do you mean? You've always had a choice whether or not to buy an iMac Pro, so if you did need the features of an iMac Pro (incl.. 5K screen, motherboard, ecc memory, 10gbit ethernet, more cores) you could just get it. It's not like Apple is preventing you from building a PC just because they released the iMac.

Except for most (probably all) uses of an iMac pro "need" ECC memory about as much as they "need" the apple logo the back of the computer. No workstation needs ECC. At least, few enough would benefit from ECC that a comparable system shouldn't need to include it.

You have that choice with the iMac too, you just get the regular iMac instead of the iMac Pro.

And then have a significantly less capable machine. The performance gap between an iMac and an iMac Pro will be large. The performance gap between this iHac and the iMac Pro will be nonexistent, even without the Xeon processor.
