I am not the poster you are replying to, but one other reason I always choose Mac Pro is the ECC RAM.
This may be mostly superstition on my part, but the fact that it can correct when cosmic rays from outer space[1] flip arbitrary bits in my computers' RAM really satisfies me.
I have tried to use spare Mac Minis or notebooks as servers, too. Among my couple dozen Macs, nothing other than a Mac Pro has ever had a > 1 year uptime when really being used.
Don't really know that it's the ECC RAM, but I'm sticking with it.
First: I have 2x30" screens. I don't want to go down.
Second: I can't put multiple HDDs and SSDs in an iMac.
The new system replaces a 24" iMac I bought in 2008. It made it for 5 years; the only upgrades were extra RAM when new and swapping the HDD for an SSD about 2.5 years into its lifetime.
I don't know how long I'll keep this one. Under Australia's small business equipment rules, it's already fully depreciated. So there's no accounting purpose to hold onto it if I don't want to.
