Compatibility and service notes
Inspect the hinged panels, latches, dust filters, fan controller and removable drive cages before moving a used case; its width/depth and mass require clearance.
- Check GPU length and thickness, its power-plug bend, cooler height and radiator/fan assembly against the same installed configuration; advertised maxima may conflict.
- Confirm motherboard standoffs match the board holes and inspect front-panel, USB and fan-controller headers before powering the build.
- Record the exact SKU, manual revision, removed brackets and unused drive hardware. Measure the individual chassis before shipping or fitting nonstandard parts.
