My real hope is Apple releases the rumored "Mac Pro mini" to fill this gap. My desktop is still a 6 core Xeon 2010 Mac Pro, which now has 32GB RAM, 2 SATA SSDs, two HDDs, and with PCIe a NVMe SSD, Radeon RX 570 that can drive 3 displays, and USB-C card, all of which were surprisingly affordable upgrades. It even runs Catalina with OpenCore (amazing software btw). Apple really needs something in between the $700 Mac Mini and $6000 Mac Pro. A somewhat larger case that opens easily and some expansion slots should not carry a $5000 premium, and no I don't want a built in display.
