Is there a heatsink that combines the Heat Pipe's condenser element external to the PC Box and couple to a Peltier cooler? Having the Peltier external to the box should not be a probelm even if it generates heat on one side.

My environment may experience high room temperature from time to time, could be as high as 38C. With a Peltier add-on externally could the CPU temp be kept at a much lower degree than room temp?

technically that's possible. However, keep in mind that the heat pipe itself must be designed specifically for this purpose (different temperature range compared to operation without peltier). Using commonly available heat pipes, it is probably of little benefit.

If you insist on using a peltier element with a heat pipe, it is better to put the peltier on the hot side of the heat pipe and let it cool the CPU directly. But keep in mind that you need a heat pipe with a very high power transport capability.

Generally, I think it's not a good idea. Designing good cooling systems based on peltier elements or heat pipes is quite a challenge. Combining the two hard-to-handle technologies doesn't exactly make things easier.
