With a $3,000 starting price, it may be hard to justify upgrading the new Mac Pro beyond its basic specs when you make the purchase. Thankfully this unit is mostly user-upgradable, including its RAM, and like always, OWC is ready to go with RAM upgrades ($75-$859). While Apple charges up to $1,200 for the maximum RAM — four 16GB chips equalling 64GB total — OWC charges $341 less for the same array.
