ITX Motherboard Layout
The ITX layout is the reference configuration for the Meshroom S V2, designed around a Mini-ITX motherboard (170 × 170 mm) with full GPU compatibility and flexible front and rear mounting options.
GPU Fitment
The Meshroom S V2 supports front, rear, and SFF GPU mounting. Maximum GPU length and thickness depend on tray position and whether additional feet are installed.
Front GPU
| Tray mode | Without additional feet | With additional feet |
|---|---|---|
| 3-slot (tray position) | 314 × 120 × 61 mm | 335 × 120 × 61 mm |
| 4-slot (tray position) | 314 × 120 × 76 mm | 335 × 120 × 76 mm |
Rear GPU
| Tray mode | Without additional feet | With additional feet |
|---|---|---|
| 3-slot (tray position) | 332 × 153 × 63 mm | 353 × 153 × 61 mm |
| 4-slot (tray position) | 332 × 153 × 82 mm | 353 × 153 × 82 mm |
* Recommended configuration for most users.
SFF GPU
| GPU type | Reference size |
|---|---|
| SFF GPU | 239 × 160 × 63 mm |
Note: Use 90° DP/HDMI connectors when GPU I/O clearance to the bottom frame is tight.
PCIe Riser Cable Length
| GPU position | Supported riser cable length |
|---|---|
| Front GPU | 145 mm or 200 mm |
| Rear GPU | 145 mm or 200 mm |
| SFF GPU | 200 mm or 220–270 mm |
Cable length selection depends on routing preference and GPU position. Excessively long cables may impact cable management and airflow.
Cooling
Air Cooling (CPU Cooler Height)
| GPU tray mode | Maximum CPU cooler height |
|---|---|
| 3-slot mode | 74 mm |
| 4-slot mode | 54 mm |
CPU cooler clearance is affected by GPU tray position. Verify cooler height including fan and top cover.
AIO Liquid Cooling
| Mounting position | Supported radiator size | Dimensional limits | Notes |
|---|---|---|---|
| Front | 240 mm / 280 mm |
Max total thickness (radiator + fan): 63 mm Max radiator width: 144 mm |
Fully supported |
| Rear | 240 mm / 280 mm |
Max total thickness (radiator + fan): 63 mm Max radiator width: 144 mm |
Depends on GPU width |
The maximum thickness of 63 mm refers to the combined thickness of the radiator and fan assembly.
Mounting the fan facing outward increases the total radiator assembly width to a maximum of 154 mm.
Rear AIO compatibility depends on GPU thickness and tubing clearance. Clearance verification is required before installation.
PSU & Storage
Power Supply (PSU)
| PSU type | Supported configuration |
|---|---|
| SFX or ATX (≤ 150 mm) |
Supports 55 mm thickness downward-tubing AIO assembly. Radiator must be oriented facing outward. |
| ATX (160 mm width) | Supports 55 mm thickness upward-tubing AIO assembly. |
| ATX (170 mm width) | Fan assembly supported. |
PSU dimensions and tubing direction directly affect AIO compatibility. Verify total assembly thickness before installation.
Storage (Drive Support)
| Drive type | Maximum supported | Mounting locations |
|---|---|---|
| 3.5" HDD | Up to 4 drives |
Rear (behind PSU): 2 Front of motherboard tray: 2 |
| 2.5" SSD | Up to 8 drives |
Top: 2 Bottom: 2 Rear (behind PSU): 4 |
The quantities listed above represent all available mounting locations within the ITX layout.
Actual usable drive count depends on whether GPU, PSU, or AIO components occupy shared mounting space.
Storage compatibility may vary based on system configuration. Clearance verification is required when combining multiple components.
The diagrams below illustrate GPU length limits for different mounting positions in the ITX layout.

Quick Compatibility Summary
• ITX motherboards provide the widest configuration flexibility across all GPU, AIO and PSU options.
• ATX and mATX motherboards require careful GPU position planning and are limited to SFX power supplies in most layouts.
• GPU length alone does not determine compatibility — thickness, height, and airflow clearance are critical.
• 4-slot GPUs require additional planning for airflow, cable routing, and internal clearance.
• Modular power supplies significantly improve build success in compact layouts.
Which Layout Should You Choose?
• Choose ITX layout if you want maximum GPU flexibility and simplified cable routing.
• Choose ATX layout if you need full-size motherboard support and are willing to plan GPU positioning carefully.
