This listing is for the Apple Mac Pro Feet Kit, a genuine Apple accessory, not a desktop computer -- it's a set of replacement feet for the Mac Pro tower, sold separately for anyone who needs to replace worn, damaged, or missing feet on their existing Mac Pro rather than buying a new stand or chassis outright. The Mac Pro's distinctive stainless-steel lattice tower sits on rubber-cushioned feet that both protect the desk surface from scratching and help keep the heavy chassis stable and level -- over time, or after moving the unit, these feet can wear, crack, or come loose, and this kit lets an owner restore the machine to its original factory fit without needing a full service visit. It's a small, inexpensive, purely mechanical accessory rather than anything with electronic specifications to list, and it is compatible specifically with Apple's Mac Pro tower chassis -- not the Mac Studio, Mac mini, iMac, or any other Apple desktop in this catalog.
