A 4750G build in the smallest brickless case available. Having changed cases for the APU so many times, I seem to have hit the sweet spot in terms of size and compatibility (not having a power brick to lug around is a game-changer).
The internals are fairly bog-standard. High-speed memory to feed the iGPU, a 2300Mhz GPU OC through the bios, and enough storage for work. I may try to add another NVME via a PCIe adapter, but not sure if it'll be too tall. PSU has a fan swap to kill the extra noise and the modular cables make these APU builds all the more simple.
The truly interesting part is the case limitations. With a max cooler height of 30mm, I had to dig out some tricks, namely a Noctua backplate and scythe 100x12mm fan for the IS-30 (only allows for a 12mm fan and the stock fan is loud AF). It also won't take an IO shield, I will probably just end up creating a mesh DIY IO shield and double-sided tape it in there. All of the plastic above the IO had to be taken off as well as it was too tall to fit.
In terms of thermals, it's not nearly as bad as you might anticipate. Even with the GPU OC, I'm idling in the low 40s and hits the high 70s under a stress test. the larger fan, backplate, and Kryonaut seem to be doing their jobs quite admirably. I've said it a million times, but the Noctua backplate kit is the best $8 you'll ever spend.
Overall, I think this is a very niche case with a lot of compromises that might not be for everyone, but it hit all the right notes for me. I have an entire 8 core 16 thread little monster in something not much bigger than a book.
