You can sell the Mac Mini after a couple of years and recoup 60% of the cost of the machines.
You've got millions of consumers who would be willing to buy a used Mac Mini. How many buyers would you have for a used Dell server?
Your source does not actually support your claim.
The Bible was written to be taken literally (to be understood by its literary genre). In other words, poetry is to be understood as poetry, historical narrative is to be understood as historical narrative, etc.
If you don't take it literally, then you're free to treat the psalms as historical narrative or the laws as poetry, etc. In other words, you could make it mean whatever you want it to.
