Everything you’ve seen from us — Aillex’s cloned voice, her 26-billion-parameter brain, the 3D avatar, the videos that produce themselves every morning at 7am — runs on one computer. Not a server rack. Not a cloud account. A prebuilt gaming PC sitting in a home office.

This is that machine, and an honest breakdown of what matters.

The exact build

An iBUYPOWER prebuilt — the RDY Y70 TI B05:

What actually matters for local AI (ranked)

1. VRAM is the whole game — 32 GB of it. Every capability on this site is ultimately a VRAM budget line: the 26B brain (~17.6 GB), speech recognition (~1.5 GB), real-time lip-sync (~8.5 GB). They run simultaneously because 32 GB gives room to co-resident models. With 16 GB you’d run a smaller brain OR the avatar — not both. If you take one thing from this article: buy VRAM, not framerate.

2. System RAM — 64 GB is the quiet hero. WSL2, model conversion, video pipelines, a dozen Python environments — we routinely sit above 40 GB. 32 GB works; 64 GB removes a whole class of mystery failures.

3. Storage — 4 TB fills faster than you think. Models are huge: our LoRA library, three video generators, TTS models and checkpoints currently occupy well over a terabyte. Gen4 speed matters less than capacity — models load once and stay warm.

4. The 1000 W PSU earns its keep. A 5090 under sustained video-generation load is not a gaming duty cycle. Generation runs hammer the card for 40–60 minutes flat. Headroom = stability.

5. CPU matters less than you’d expect — with one exception. Inference lives on the GPU. But our text-to-speech runs entirely on CPU (that story here) precisely to keep VRAM free — and the 24-core i9 doesn’t blink at it.

Honest notes on prebuilt vs self-built

We didn’t plan an “AI workstation.” This was bought as a gaming PC — the AI obsession came after. That’s actually the point: the machine you may already own (or can order assembled) is enough. No used datacenter cards, no Threadripper tax. One warranty, one box, GPU arrives packaged separately (install it yourself — it’s four screws and a cable).

Could you part-pick the same spec cheaper? Somewhat. Would we trade the 3-year warranty and the working-out-of-the-box on a machine that now runs a 7am production pipeline unattended? No.

What we’d change (2026 edition)

  • More VRAM, always — if a 48 GB consumer card existed at sane pricing, we’d own it. Watch this space.
  • Second SSD from day one. You will fill the first one.
  • Everything else? This box has rendered thousands of images, hundreds of video clips, and an entire self-producing YouTube channel without a single hardware complaint.
