This mini PC is definitely worth my money as it delivers more power than I expected. It is easy to install and has various IO ports and runs smoothly. Note that the i5 8259u used in this model is even more powerful than i3-8100! I noticed that on the benchmark websites before I made the purchase. And there has been a YouTube video comparing this NUC 8th gen i5 with hackintosh build against the i3 Mac Mini 2018. It shows that this smaller intel PC is even more powerful than the Mac mini! In some applications the NUC is almost 35% faster than the Mac mini.The cooling is ok. You can’t expect it to be as cool and quiet as a custom PC with a high TDP cooler. But it does a good job and the temperature looks reasonable. It is around 36 Celsius when idle, around 55 Celsius when running light weighted applications. And the highest temperature is around 80 Calcius for intensive computation tasks (when the fan noise becomes significant). I don’t see an obvious throttling issue, and usually it runs at almost full turbo boost speed (3.7GHz).In one word, I really love this mini computer and find it really capable and competent for my need. The only pity is that the price dropped by $40 one week after I bought it.
