I’ve just measured mine and you have 310mm clearance from the backplate to the rear of the front stock case fans, so an FE card will fit easily as will a lot of the triple fan cards like the Evga XC3 cards etc. Just check the specs. ## Frequently Bought Together - Cooler Master Silencio S400 mATX Tower W/Sound-Dampening Material, Sound-Dampened Steel Side Panel, Reversible Front Panel, SD Card Reader, and 2X 120mm PWM Silencio FP Fans - AMD Ryzen 7 5700G 8-Core, 16-Thread Unlocked Desktop Processor with Radeon Graphics --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/159163875-cooler-master-silencio-s400-black-tower-case-m-itx-m](https://www.desertcart.co.uk/products/159163875-cooler-master-silencio-s400-black-tower-case-m-itx-m) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-09-13*
