Common themes:

  • Processors in back corner, opposite side to connector with high power drives
  • High power drives aligned to extend away from the connector, not across it
  • SMD drivers and/or vertically mounted reinforced to220 drivers
  • High power tubular SMD resistors
  • BDM connectors on the edge
  • Both sides heavily populated
