JSAUX ModCase for Steam Deck LCD & OLED
JSAUX ModCase for Steam Deck LCD & OLED: Modular protection with cooling, docking, SSD, and power accessories for full-deck versatility.
Modular Protection That Does It All
Published by HandheldModz · November 2025
The JSAUX ModCase for Steam Deck LCD & OLED isn’t just a protective shell — it’s a modular ecosystem designed to upgrade your handheld experience. With precision-cut components, eco-friendly materials, and compatibility with multiple add-on kits, the ModCase lets you customize your Deck setup for travel, performance, or power-play sessions.
🧱 Key Features
Complete and Flexible Protection
Each ModCase includes a back case with metal stand, a strap system for accessories, and a front cover for when your Deck is idle. Together, these parts form a complete protection and mobility solution.
Perfect Fit, Every Port Aligned
Cut-outs are perfectly matched to the Deck’s output/input ports, ensuring full access without interference.
Built to Protect
Made from eco-friendly PC-ABS and silicone, the ModCase shields against drops, scuffs, and shocks. Its TPU-reinforced edges absorb impacts, while the front cover prevents screen scratches when stored in a bag or backpack.
Modular Expansion — The More, The Better
At the heart of the ModCase is a modular back-slider, letting users attach optional accessories like cooling fans, hubs, SSD enclosures, or even a high-capacity power bank. It’s not just protection — it’s a platform.

🧩 Why It Stands Out
The JSAUX ModCase bridges form and function. It’s durable enough for travel yet modular enough to become a portable workstation when paired with its accessories. Whether you’re cooling the Deck during extended sessions or expanding storage for your library, every piece clicks into place with purpose.
