Plan your service · Cedar Hill
Choose the intake route before moving a large tower.
A full-size gaming case can be awkward to transport, especially with a glass panel or heavy graphics card. Call the receiving branch with the case and cooling details. We can confirm the receiving location and which equipment should accompany the PC.
- Tell the branch about a large case, glass side panel, heavy graphics card or custom liquid-cooling loop before arranging transport.
- Ask whether the tower alone is enough or whether a particular monitor, display cable or adapter is needed to reproduce the fault.
- Keep loose accessories separate and secure the PC for travel; ask for model-specific handling advice before removing internal parts.
Important files on the PC? Mention them before resets or reinstalls. Review data recovery options.
