Chicken-coop shed AI PC

Saw soneone post their bathroom AI PC a few weeks ago. Figured I’d contribute with my chicken-coop adjacent shed AI PC. Started with a single CMP 170HX (unlocked to 64GB) and ended up with three more for a total of 256gb VRAM. Found a deal on a used Threadripper with a TRX40 motherboard and 256gb DDR4 RAM to host the 4x 170HX. Added a 3050 plugged into riser connected to a NVME slot for video/RDP. My case ran out of space so that’s the board dangling freely lol. My original goal was to save money by running AI locally. Naturally, this escalated into four 170hx, a 32 core Threadripper, and enough RAM/VRAM to turn my hobby into what my wife says is a financial liability… oof. Originally had it in a closet, but between the heat and the wife complaining about the noise, the GPUs were eventually banished to the shed. Now they are in a happy place with A/C and 2x 20amp receptacles on separate circuits. One for each power supply. No more fan curves to reduce noise either. Running QFN split between two of the 170HX with capacitor mods and Qwen3.8-27B on the third. Just got the 4th 170hx installed today. Downloading GLM 5.3 Flash EXL3 4.65 bpw to see how it’ll run on all 4. Really looking forward to seeing how this beast will handle Qwen4. QFN does so much so well that I can’t imagine what Qwen 4 will be like. submitted by /u/sevendaysworth [link] [comments]
