Compact 16.8L Micro-ATX Chassis

The Shiny Snake G300 is a white 16.8-litre case built for Micro-ATX and Mini-ITX motherboards. It targets builders who want a small-footprint system without sacrificing high-end component support. The mesh side panel and SPCC steel construction prioritise airflow and a clean aesthetic. It suits enthusiasts assembling a portable gaming rig or a powerful workstation in a minimal volume.

340mm GPU and Dual Cooling Paths

This case replaces larger mid-tower enclosures when desk space is limited but flagship graphics cards are required. It fits 340 mm long GPUs such as the RTX 4090, 5080 and 5090 while supporting CPU air coolers up to 164 mm tall. For liquid cooling, an SFX or SFX-L power supply unlocks 240 mm or 280 mm AIO radiator support via the included bracket kit. The jump is worth it when a full-size ATX build is impractical yet a 4-slot card and high-wattage CPU remain essential.

Drive Bays, I/O and Clearance Limits

Internal storage consists of one 3.5-inch bay and one 2.5-inch bay, sufficient for a primary SSD and a bulk hard drive. Front I/O provides USB 3.2 Gen 2 Type-C at 10 Gbps, two USB 3.0 ports, two USB 2.0 ports and audio. Four expansion slots accommodate the thickest cards. The 140 mm ATX power supply limit and 340 mm GPU ceiling define the headroom; builds needing more drives, longer cards or larger radiators will exceed the chassis capacity.

Questions about this item

What are the exact GPU length and CPU cooler height limits for the G300?

The case accepts graphics cards up to 340 mm long and CPU air coolers up to 164 mm tall, covering cards such as the RTX 4090, 5080 and 5090.

How do I switch between ATX and SFX power supply mounting, and what is the common mistake?

Remove the top bracket and reinstall it in the SFX position; the step people miss is fitting the included SFX bracket kit before installing a 240 or 280 mm AIO, otherwise the radiator will not clear the PSU.

How often should the mesh side panels and front dust filters be cleaned?

Vacuum or rinse the mesh panels and the front dust filters every three to six months; the mesh design cuts dust intake by about 60 percent compared with solid panels, so buildup is slower but still needs periodic removal.
