Seems like a pretty decent rig. Personally I'd probably up the RAM and SSD, but that does eat into the value.
You can up the RAM to 32GB for $139 and the SSD to a SN750 1TB for $129
There's also an option to swap the CPU Cooler to a 120mm RGB AIO Cooler.
There seems to be only one cheapish 3080 TI on market, the rest are $2499+
