Plan the installed configuration
External case dimensions do not establish GPU or cooler clearance. Internal limits can change with drive cages, radiators and fans. A case name alone cannot confirm a complete fit.
Before choosing parts
- Verify supported motherboard and PSU form factors in the case manual.
- Measure GPU length, thickness and power-cable space with the planned cooling installed.
- Check CPU cooler height and radiator thickness as separate limits.
