Pump (and fans) lasts longer if they are running at a set rpm rather than increasing and decreasing rpm regularly. Pump is fine at 100%, and fans depends on the load and the kind of fans, as some are higher rpm and/or cfm than others. If you don't care about noise and want the absolute best thermals, go max rpm. Otherwise, one of the best things about a bigger aio is to have the fans run slower and producing less noise, while still offering good cooling.
Unless it is loud let it run at full speed. The pumps wheel is tiny, it often runs at 3-4x the speed of the case fans. As for the radiator fans: keep them around 1000-1200rpm for silent running and rump them up if your cpu temperature goes above 60°C! If it is a 120mm radiator you can remove one fan without further ado. Otherwise make a test run with on fan. Nothing can go wrong, but if you are not satisfied with the cooling capacity mount the radiator to the top!
The GPU is fine for light and casual gaming, perfect for an Optiplex with an F sku CPU (I have a habit of buying dirt cheap Optiplexes for the i7 to upgrade a gaming rig with an i3 (basically free i5 is good as well).
Less stress on the actual hardware, bearing, motor, etc. The fans typically handle it better unless you have major swings in rpm on a couple degree increments. Pumps have to deal with the increased stress from the water, both spinning up and slowing down. The manual should have a section on the preferred speed it should run at, though you can experiment. If you have a quiet pump, running it at 100% is perfectly fine. If it's a bit noisier, running it at 50/60/70/whatever% speed is fine, so long as temperatures are fine.

yes it pump was running quiet at 100%
By the way, who knitted the star afghan hanging on the wall?
My mom made it
@rohon4972 It's quite nice.
