Josh, You are are not very serious. You are sending me a CPU that has completely different hole pattern (see gold looking holes) and I cannot use. I am asking you if the MK2 standard and the MK2 extended has the same CPU and you cannot answer??? THAT IS COMPLETELY UNACCEPTABLE. MY MACHINE HAS BEEN DOWN FOR MORE THAN 5 MONTHS AND YOU CANNO0T HELP. I PURCHASED 3 ADDITIONAL CPUS AND YOU CANNOT TELL ME WHY IT IS CLANKING??? DOD YOU SELL ME EXTENDED CPU INSTEAD OF STANDARD?? GIVE ME THE ADDRESS OF THE STORE WH CAN FIX MY MACHINE IN THE USA OR GIVE HALF PRICE ON A NEW ONE, OR I WILL CALL MY LAWYER AND POST NEGATIVE REVIEWS OF YOUR CUSTOMER SERVICE.
