Overview

The Streacom ST-FC9S Alpha Fanless HTPC Case is a silent, fanless enclosure designed for media center builds. Its construction combines aluminum and polycarbonate, resulting in a sleek, silver chassis that weighs only 1 kg. The case supports a slim optical drive, making it ideal for movie and music playback in a living room setting. This product is positioned as a premium solution for users who require absolute silence from their PC.

Compatibility Guide

This case is compatible with Mini-ITX motherboards only. The power supply must be an SFX unit; standard ATX power supplies do not fit. Storage is limited to one 2.5-inch drive (SSD or HDD). For CPU cooling, only low-profile heatsinks or purpose-built passive heatsinks can be used due to height constraints. Graphics cards are restricted to low-profile, short-length models. The case includes a slim optical drive bay, enabling CD/DVD playback.

Pricing is in the ¥80,000 range (approximately $550 USD), placing it in the high-end segment for fanless cases. Warranty is typically one year from the manufacturer. This case occupies a unique niche: it is not for high-performance gaming but excels in silent HTPC or office PC setups. A purchase link is provided below: View on

Best Use Cases

Silent HTPC: Perfect for streaming movies, music, or running a home theater system with zero fan noise. Office PC: Ideal for quiet environments like libraries or open-plan offices where noise is unacceptable. * Light-duty secondary PC: For basic tasks such as web browsing, document editing, or file serving, this case provides a compact and silent solution.

Things to Consider

The most significant limitation is thermal headroom: the case relies entirely on passive cooling, so CPU TDP should not exceed 35W (recommended Intel T-series or AMD low-power chips). High-performance CPUs will overheat under load. GPU support is equally constrained; only low-power, low-profile cards fit. Additionally, SFX power supplies are required, and the slim optical drive must be sourced separately. If you plan to game or render video, this case is not suitable. Ensure your components are fanless or very low power before purchasing. ## Specifications | Item | Specification | |------|---------------| | Brand | Streacom | | Model | ST-FC9S-ALPHA-OPTICAL | | Color | Silver | | Material | Aluminum, Polycarbonate | | Motherboard Support | Mini-ITX | | Power Supply | SFX | | Optical Drive | Slim slot-loading | | Storage | 1x 2.5-inch | | Weight | 1 kg | | Cooling | Fanless (passive) |
