The CPU and GPU are both AIO water cooled.
The CPU is well binned, holding an overclock of 5.0 Ghz for a 19% speed increase over base clock.
The twin 970 EVO NVMe SSDs are in hardware RAID0 for ~7000MB/5000MB sequential read/write speeds.
There are some extra cables and accessories that can come with, such as the NVIDIA Founders Edition Cooler.
This PC was not used for crypto currency mining.
I can prove parts and demonstrate operation on pickup.
