The Mercury EM680 Mini PC looks good but I'm concerned about poor cooling and noise, can anyone help me with this concern?

I'm wondering if the EM680 is smaller than a regular mini pc, and does that CPU performance suffer?

Dear customer， EM680 Mini pc only 1/4 L, 1/120 of the volume of the desktop with AMD Ryzen 7 6800U, 8 cores/16 threads(16M L3 cache, up to 4.7GHz), AMD Radeon 680M (graphic frequency 2200MHz), capable of handling gaming, programming, and daily office tasks with ease. Attached EM680 video for you! Best regards Anna

Does the hx99g support 120hz or 144hz through hdmi at 1080p? i see that it's 60hz at 4k but i would assume something for gaming could output more.

I think that’s the limitation of this computer. 60hz @4K. If you need to look for more then this is not the desktop for you.

Can additional ssd be added by just removing the top cover? Also, would this void the warranty?

Dear Friend. Good afternoon,You can see how to c disassemble (replace RAM and SSD) by following link https://www.amazon.com/live/video/0b93fb9a90004ed295af70ecadacbfc3 Regards MINISFORUM SERVICE Melody
