Review on Cooler Master MasterAccessory ARGB GPU Support Bracket - Enhanced with Edge-Lit ARGB Tempered Glass, Universally Compatible GPU Bracket with Adjustable Orientations by Darian Massey

Easy installation and beautiful appearance, can be synchronized with cabinet lighting to produce consistent RGB lighting. I would recommend an RGB hub if you don't already have one installed in your case if you plan to use RGB on a stand. I really like how easy it was to position my hand exactly where I wanted it under the GPU. The hand is locked and feels extremely durable. You can also choose different positions depending on how you want the stand to look in your case if you're worried about blocking airflow. The base is also magnetic so you don't have to worry about the stand moving around. Very well done by CoolerMaster. I highly recommend this product to anyone worried about GPU slack for the monstrous RTX 3000 series GPUs.
