I just ordered a refurb iMac 5K 27" Retina display, 3.5 GHz, 1 TB fusion drive, 8 GB RAM. The price was very attractive ($2119.) so I pounced. I bought an extra 8 GB RAM from OWC so that will bump it up to 16 GB. For everyone's information, the salesperson told me that migrating data would be faster using FW - Thunderbolt (Target Disk Mode) than via Ethernet. This may be useful for someone else.
