RTX 2080 Ti is definitely not a good choice - the cards do not stack and they draw way too much power (enough to damage the motherboard.) And why do you want to use a 6U chassis with PCIe risers for only 4 GPUs? You may want to check out Sagitta HPC since you don't really seem to know what you are doing.
