    Hey, gang. I'm building an emulation machine to live in a shared cabin in the woods. It can't take up much space, so I'm looking at a mini ITX build without a graphics card. It's also going to be living at this cabin where I won't be able to easily run up to fix or replace anything, so I want to stick to air cooling for the system.

    The Ryzen 7800x3d seems like the best contender for processor, but I'm having a hard time settling in a case. The Inwin Chopin Max seems like its 200 watt power supply should do the job, but Inwin has a list of CPUs that the case will work with and some pretty stern warnings about trying something else. Is Inwin's website just outdated, or is there something else that I've missed?

    A 7800X3D does not use much power, and will not heat the case up much, however it does require a somewhat large air cooler.

    The chip is sitting under a layer of cache, through which it must transfer the heat. A D15 is overkill (and about right for a 7950X3D), but it should be a decent cooler, which usually means not small. I would determine what kind of air cooler will actually fit before you get that case, it is likely it is not a great fit for this use.

    Despite the Ryzen 7000 CPUs having an iGPU, my understanding is it's not really sufficient for any but the most basic of desktop functions. Even an emulator app might overwhelm it. If a dGPU card is really not an option, I'd be looking to get something in the Ryzen 8000G family instead, probably the 8700G or 8600G but really any should do I'd think for an emulator box. Power requirements and heat generation for the 8000G CPUs should be in line with that of those listed as compatible with the Inwin case (though I'm not sure if the included heatsink is compatible, an aftermarket one may be required).

    Thanks! After posting I was doing some more research and it does seem like an 8700G might be better, though I also started looking at the 7840HS. I'm shooting for Xbox 360 emulation.

    I also started wondering whether I should just put this off until the Fall when the new APU generation comes out. It seems like the 7840HS and the 8700G can do Xbox 360 emulation pretty well, but a generational leap probably will make that rock solid.

    The two have very similar specs, the 8700G does clock higher in base clock and iGPU, and is also overclockable (AI/TOPS performance is also far better, FWIW). Going with the 8000G/AM5 platform also will possibly allow for upgrading to the next APU generation in a couple years should that be desirable. Being a laptop/soldered piece, you can't do that with the 7840HS. I'd also be a bit wary of 7840HS systems having low/non-configurable TDP settings due to small packaging/heatsinks, possibly limiting performance.
