In BBT's latest Livestream the team covered a pretty interesting 2x Pro Duo (Fiji) build in a highly modified version of our open air frame case. The case was painted in Crimson Red and featured mounts for the dual watercoolers. The testing as shown in the episode showed some pretty good numbers (Eth and DCR), however at the expense of some serious power usage. The AMD Pro Duo card does require 3x VGA 8-Pin connectors per card and when dual mining exceed the maximum spec's of our power-supply. We have since swapped that out to a eVGA Supernova 1300 G2 PSU to handle the near 1100w requirement when dualmining.
