Greetings,

I unfortunately acquired an Optiplex 9010 with a core i5-3550.  To make a long story short, after troubleshooting why the system would not boot up (checked cables, fans,connectors, etc.) I discovered that the CPU socket has some bent pins.  While none look crinkled to the point of not being able to be repaired, the repair is no longer something I can do myself; carpel tunnel and deteriorating eyesight are not fun. 

Anyway, the 9010 I have is the mini-tower version, so I am simply wondering the part number to find an affordable used or refurbished motherboard.  I would just like to know if the version I am seeking ( an exact replacement to my current system) is indeed the 051FJ8/51FJ8 version.  I understand that perhaps not buying directly from the manufacturer may be frowned upon, but my budget is virtually non-existent and I need this computer working for college purposes. 

Any help would be greatly appreciated!  Thanks in advance!
