TLDR: I've been leveling up my orchestration process and productivity. I'm on three Claude 20x plans and my biggest bottleneck is that I simply don't have the compute. My laptop can't handle the processes I'm doing and it would also be good to have something on 24/7, working when my laptop's off, etc. Would really appreciate anyone who's been in a similar situation and made a good decision/bad decision, or just any sort of knowledge on that front. Would really appreciate a little slide into the DMs, pointing me in the right direction. I'm non-technical and I just want to make a good decision ;] Here's a Claude summary of the situation that we've had a conversation about: I’m in the UK with a budget of about £1,000 (secondhand is fine). I want an always-on machine under my desk to take my AI agent workloads off my laptop. At the moment everything runs on an i7-1355U laptop with 16 GB of RAM, and only about 3 to 5 GB of that is free for the work. I’m running Claude Code, Codex and similar agents, plus automated website builds (node, pnpm, headless Chrome). I want to run about 10 of those jobs at once and reach the box from my laptop or phone, including on the move, probably over Tailscale. The jobs mostly wait on model calls, so memory and core count matter more to me than single-core speed. I already have an 8 GB, 2 vCPU VPS, but it’s slower than my laptop, so I’ve ruled it out as the main machine. I’m leaning towards a used Ryzen 9 5950X build on AM4 with DDR4 (16 cores, 64 GB, roughly £730, with 128 GB possible if I can find a sensible price). I’ve also looked at used Xeon workstations (HP Z4, Lenovo P720) and Threadripper builds. The Threadripper builds and dual-Xeon towers look over budget once I add decent RAM, and the older Xeon Gold chips aren’t Windows 11 compatible. I plan to start on Windows 11 Pro because my tooling is Windows-specific, and then add Linux on a second drive later. I’ll want room for a GPU later, since local models are a longer-term interest, and I’m not worried about noise or power draw. I’d like advice on CPU and platform choices, whether 64 GB or 128 GB is the right target, any memory and platform traps for AM4 versus used server gear, where you’ve had good luck buying used, and anything I’m missing.
