Excellent price for refurb, system delivered on time and pretty much as described. Instead of i7-4770, it came with the i7-4790, instead of a 2TB it came with a 3TB and then the DVD-ROM was a RW.  The downside, the DVD would power up but wasn't recognized by the system. No response from vendor support, but easily fixed with a cable swap. The 3TB was MBR formatted so only saw about 740MB. Needed to convert to GPT to get access to whole 3TB. Add 500GB SSD, clone OS over, so low risk of losing anything in the repartioning.
