Two full-height glass panels, four 140 mm fans, room for two 420 mm radiators: Pause Hardware found “a gem” in the Radiant.X, and awards it two distinctions at once.
"Oh, what a gem!!"
That's the title Pause Hardware chose for its test. It sets the tone.
The Radiant.X picks up the panoramic case trend, but does it properly: full-height tempered glass, on the front as well as the left side, held by a thin strip of black steel, with the logo set vertically. The side glass is nearly 4 mm thick.
A 52.5 cm full tower, it takes an ATX, micro-ATX or mini-ITX motherboard, a 455 mm graphics card and a 185 mm CPU cooler. Four 140 mm ARGB fans are already fitted.

The scores, one by one
Pause Hardware rates seven criteria. Here's what lies behind the best of them.
Elegant without overdoing it
Panoramic dual-glass view, vertical logo on the front, black steel band along the edges: the reviewer praises a fish tank with character, in black as well as white.

Two 420 mm radiators
One on top, one on the right-hand side of the motherboard, in 3 × 120 or 3 × 140 mm, with 60 mm of clearance up top. A 140 mm can be added at the rear. Few cases at this price take that many.

Everything is in the box
The hub drives six PWM fans and seven ARGB elements, a remote controls the lighting, and a bracket supports the graphics card — movable for vertical mounting, with 83 mm of clearance. On the front, a USB 3.2 Type-C port.
A hassle-free build
Around 30 mm behind the tray to tuck cables away, wide and well-placed cable routing holes, and up to eight drives on removable mounts. The test build fits in "without any trouble".

Three reservations
The review doesn't overlook what's missing, and neither do we:
the fan bracket to the right of the motherboard isn't removable;
no E-ATX motherboard support, despite the size of the case;
at full speed, the fans are audible — 56.1 dB(A) measured at 50 cm.
What Pause Hardware says about it
In short, nothing has been overlooked and the M-RED RADIAN.X stands out as much for its versatility as for its elegance.
