QuoteRepairs are difficult, however, because the internals are heavily glued in place.

Opening the charger is impossible without destroying the case. That alone makes it not worth it, especially considering the price. Then, everything is glued (this is ok, since it protects again vibration and helps dissipate the heat) and hidden inside + even this guy couldn't fix it, maybe because of these reasons.

But a cool video, to see what's inside and whether the design is safe, nonetheless.

Salvaged, old and power inefficient Xeon CPUs. Even today Xeons, due to Intel's bad node, can't compete with AMD's Epyc CPUs, hence why AMD's server market share is growing (plenty of news about it). Consumer Panther Lake did improve its iGPU power efficiency a lot, but the iGPU chiplet is made by TSMC. That being said, it might not be even be a node issue for Intel: Hardware Unboxed tested a Intel CPU (was it its iGPU?) made by TSMC and its energy efficiency still didn't improve.
