Not so big after all, but the quality is there and the design is a success
Superb! First impressions: it's heavy, solid, well thought-out, all the screws can be removed by hand, and there's a handy rear frame for routing the power supply. There are dust filters everywhere (sliding underneath and magnetic on top) and another good point: 3 large 140mm fans that can be fixed in several places. That's a nice touch!
I installed an ATX Asus TUF Gaming B650+. This ATX format fits and as the case is wide, the graphics card (4060) and the processor fan fit in easily. However, there's not that much space left and I had to remove all the removable parts to fit my Seasonic Connect 750 Gold power supply (100% modular) because of its remote connector bar. It's a bit tricky to fit, but hey... this case is pretty compact and I'm happy with it.
One last word on the glass and LEDs, because that's why we chose it. The glass is thick and there's a button on the front that lets you choose between several colour modes for the RGB strip: monochrome that scrolls from top to bottom (all the shades are selectable) or multicolour. I'm not usually a fan of 'matte my beautiful leds everywhere' type boxes, but I have to admit that this is quite successful, as the light from the strip illuminates the interior and you can see the reflections through the glass. You can also simply turn it off.
In short, I'm very happy with the result once it's fitted.
