With only 240w of total heat dissipation performance, you can bet this will be throttling like crazy. A desktop RTX 4070 can easily use 200w under load, not to mention a i7 14700k can easily use over 200w when all cores are going full tilt. This mini PC would need over 400w of heat dissipation performance if you wanted to utilize the full performance of its hardware.
It might have moderm desktop class parts, but the truth is this PC is going to perform the same as a laptop with a mobile class i7 and a mobile RTX 4070 (which is basically just a desktop 4060). For the money you can get a better PC.
