Bought one from a different seller, and the two Display Ports went out. Replaced it with this one. Upgraded it with a  1 tb SSD, and a standard 2 tb hard drive for backup and data storage and took the ram to 64 gig. Changed the allotted ram to the video in BIOS to 256 meg. Only difference between this and the original is that this has the I5, instead of an !7. Run two 28" monitors and works great.
