MSI MPG Gungnir 300R Review

If you want a glass-showcase RGB case with four fans included for under $120, the MSI MPG Gungnir 300R is one of the best-value options right now.

MSI stuffs four ARGB fans in the box, a rare count at this price, wrapped in front-and-side panoramic glass that's normally reserved for pricier cases.

Value Proposition

Four 120mm ARGB fans (three front, one rear) come pre-installed and synced to MSI's Mystic Light ecosystem if you're already running an MSI motherboard, saving a real fan-buying budget for other parts.

Comparison to Alternatives

It undercuts the Corsair iCUE 5000T RGB and NZXT H9 Elite on price while matching their glass-showcase looks, though its 340mm GPU clearance is tighter than either, worth checking against your card's length.
