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
