Pretax cost as configured: $51,999
Cost fully maxed out: $53,948
BTW, this refurbished Mac Pro represents a savings of 15% off of $51,999.
A little voice in the back of my head wondered... are these really used machines?
I thought this because a lot of new products on amazon have a fixed MSRP, but the same product used can be lower, so folks sell "used" products at a discount that still have all the shrink wrap.
