Dell XPS 8930 — PCIe x16 slot with room for full-height GPUs, PSU is the limit

The XPS 8930 has a PCIe x16 slot and enough room for full-height, double-width GPUs up to about 10.5 inches. Just keep an eye on the 460W or 500W power supply — it’ll limit how much GPU you can realistically throw in there.
