My first Imac (WooHoo) and it actually arrived by the delivery window. 4.0GHz QC i7, TB up to 4.2GHz 32GB 1867MHz DDR3L (4x8GB) - work is paying for the ram 1TB Flash Storage AMD Radeon R9 M395X w/4GB Open box. Turn it on. My poor Imac just constantly chimes and restarts to a black screen (no logo). Called support. Reset NVRAM. Reset the SMC. Nothing same constant restarting. It needs to go back.
