Budget
NVIDIA GeForce RTX 4060 Ti 16GB
$44916GB VRAM at only 160W TDP, the efficiency king for always-on servers. Runs 7-8B models at full speed and 14B models at Q4. At ~$15/month in electricity (24/7), this is the cheapest card to operate as a server GPU. The RTX 3060 12GB was considered but 4GB less VRAM limits you to 7B only.

The Rest of the Build
AMD Ryzen 5 7600 (non-X)
65W TDP. 6 cores are more than enough for serving one model at a time to a household. The non-X variant runs 20W cooler than the 7600X at near-identical inference throughput. Low idle power (~25W at socket) matters when the box runs 24/7.
500GB Kingston NV2 NVMe (OS) + 4TB Seagate IronWolf HDD (data)
Split OS/models on NVMe for fast boot and model loading. 4TB IronWolf HDD for NAS-grade data storage, designed for 24/7 operation with 180TB/year workload rating. Models live on NVMe, documents and media on HDD.

7 AI models benchmarked on this exact hardware configuration.
10 months
to pay for itself
If you're spending ~$80/month on cloud AI APIs, running locally eliminates that cost entirely. After 10 months, every dollar saved is yours.
Based on a 3-person household using ChatGPT Plus ($20/mo each = $60/mo) plus occasional API calls for document processing (~$20/mo). Budget Home AI Server at $1,162 including electricity (~$15/mo for the budget tier at 250W average). Break-even includes electricity. After break-even, savings are $65+/month indefinitely. Privacy benefit: no family conversations, documents, or voice recordings leave your network.
Home AI Server
Always-on local AI server for a household or small team. Runs Ollama + Open WebUI accessible from any device on the network. Serves chat, coding assistance, document Q&A, and transcription to multiple simultaneous users, with zero API costs and complete data privacy.
9 GB headroom for additional workloads
Upgrade Path
Swap GPU to a used RTX 3090 24GB (~$800) for 8GB more VRAM and 3x the memory bandwidth (936 GB/s vs 288 GB/s), enabling 32B models. TDP jumps from 160W to 350W, so upgrade PSU to 750W. Add more IronWolf HDDs for expanded NAS storage.
