Meshroom S / D Build Guide for mATX Motherboard + 4 × 3.5" HDD + SFX PSU

• Meshroom D natively supports only ITX motherboards.
• To install an mATX motherboard, the Expansion Bracket is required.
• This layout reduces GPU clearance — please refer to this guide link

• The SFX PSU mounting area can accommodate up to 3 × 3.5" HDDs, but careful SATA and power cable management is essential.
• AIO liquid coolers cannot be used in this configuration — you must opt for an air cooler.

• A 4th HDD can be mounted at the top of the case.
• However, this location may conflict with CPU air cooler space
