LIAN LI Vertical GPU Holder Kit (Gen5 Riser Cable, 4-slot) is a universal vertical GPU mount designed to let you display a desktop graphics card upright in many ATX-class PC cases. It supports GPUs up to four expansion slots thick, connects to the motherboard via a PCIe x16 riser cable (Gen5-ready for high bandwidth), and uses a sturdy steel bracket to avoid sagging or deformation. The kit offers a clean, premium look, especially useful if you have a glass-side PC case and want to showcase your GPU, while preserving full PCIe connectivity and performance.
