Open-Air GPU Systems: AI, Mining, and DIY GPU Rigs

Home /

Open-Air GPU Systems

Open-Air GPU Systems

Maximum GPU-per-dollar. Open-air GPU systems put every dollar into GPUs and VRAM instead of an enclosure: an open frame, spaced full-height cards, and honest engineering. Rack-shelf mountable (an open frame, not a rackmount enclosure), assembled and burned-in by eRacks.

Open-Air AI Servers

The eRacks/AIRLIE (2-4 GPUs) and eRacks/AIRA (3-6 GPUs, 6 by quote) run large language models (LLMs) on hardware you own, with the open-source AI stack (Ubuntu, Ollama, Open WebUI, vLLM, Podman (or legacy Docker, your choice)) pre-installed. Your choice of riser (the cable linking each GPU to the board): USB x1 for single-model serving, or PCIe x8/x16 for multi-GPU models and fine-tuning.

GPU Mining Rigs

The original open-air workload: purpose-built cryptocurrency mining rigs, configured to your coin and hash-rate targets.

DIY and Custom GPU Builds

Homebrew a multi-GPU box on your own terms: we supply the frame, board, risers, and power engineering (dual-PSU and 240V options included), you bring the ambition. Ask us for a custom quote.

eRacks/MINER6

eRacks/MINER6 is a pre-built, pre-configured 6-GPU open-air cryptocurrency mining rig: frame, power supplies, risers, and your mining OS and software installed, burned in, and hash-verified by eRacks before it ships. Tell us your coin and hash-rate target and we spec the GPUs to match.

Starting at $3395

eRacks/MINER8

eRacks/MINER8 is a pre-built, pre-configured 8-GPU open-air cryptocurrency mining rig for serious miners: frame, dual power supplies, risers, and your mining OS installed, burned in, and hash-verified by eRacks before it ships.

Starting at $4395

eRacks/AIRLIE

eRacks/AIRLIE - Open-frame AI inference server (2-4 GPUs). Single-socket AMD EPYC, up to 1.5 TB DDR5 ECC RAM, up to 4 full-height GPUs, generously spaced on a 6-GPU open frame. Default config: 2x Prosumer GPU (24-32GB). Runs Ollama, LLaMA, DeepSeek, and vLLM locally. No cloud fees, full data privacy, fully configurable.

Starting at $13995

eRacks/AIRA

eRacks/AIRA - Open-frame AI server for 3 to 6 GPUs. Single-socket AMD EPYC, up to 1.5 TB DDR5 ECC RAM, up to 6 full-height GPUs (6-GPU builds by quote), spaced on an 8-GPU open frame. Default config: 3x Prosumer GPU (24-32GB). For LLM hosting, fine-tuning, and high-throughput inference. No cloud fees, full data privacy, fully configurable.
