Use a reinforced double-walled heavy-duty box rated for high-value electronics. Wrap the system in 100mm+ anti-static foam or high-density protective material. Ensure no internal movement of the system during transit. If fitted, remove high-end GPUs (RTX / workstation / multi-slot cards) and package separately in anti-static bags where safe. Secure all PCIe components and internal hardware before shipping. Do not include monitors, peripherals, storage devices or accessories unless requested. Seal all seams using industrial-strength parcel tape. Remove all previous courier labels. Use a fully tracked and insured courier service for high-value hardware. Important Notice Due to the extremely high value of specialised GPU workstation systems, Green Tech Repairs cannot accept liability for damage caused by inadequate packaging during transit. I confirm I will package my Workstation Specialised / High End GPU securely before shipping.
