Thanks for your answer. I'm aware of these systems (my office workstation is an EliteDesk) however, these systems are not suitable for me for various reasons.

I make staggered updates and these systems are not very receptive for that. I wouldn't want to change my case just to upgrade the motherboard and the CPU. Also, I'm not sure that a small EliteDesk tower can accommodate all my disks (2HDDs plus 2SSDs) neither space, nor power-wise. I also use a PCIe sound card (for sound quality reasons) which needs a PSU connection via floppy connector.

At the end of the day, these systems are very nice as-is, but I need to get them as a package and they're not very flexible. My desktop usage scenario and update path is not very suitable for that.

Last but, not the least; I like to build my own desktop computers.
