Review: ちょっと短い・・・ - 4ポストラックに2Uのラックサーバを取り付けようと思って購入．ですが，ちょっと短い．説明書には「2cm伸びる」とは書いてありましたが，その部分はリベットで固定されていて絶対に動きません．その分，☆を一つ減らしました． その代わりなのか，ラックにネジ止めする「エクステンダー」が4個付いていまして，そのうちの2個を使って伸ばして解決しました． それがなければ，ラックへの取り付けは比較的簡単（道具は要らない）です．DELLやHPのレールほどじゃないですけれども．
Review: Il remplit parfaitement sa fonction - Associé à un boitier de la même marque, le montage sans outils se fait en un temps record. Le kit semble de plus de très bonne qualité.

### ⭐⭐⭐⭐⭐ Il remplit parfaitement sa fonction

Associé à un boitier de la même marque, le montage sans outils se fait en un temps record. Le kit semble de plus de très bonne qualité.

### ⭐⭐⭐⭐ Algunos inconvenientes menores
*by V***M on 1 July 2023*

En general una caja de calidad, que hace lo que debe. Le quito un punto por el sistema de ventiladores. Usa ventiladores 80x80x15, que ya es un tamaño difícil de encontrar. Y cambiarlos es un engorro tremendo. Los tornillos de abajo es casi imposible quitarlos por estar demasiado pegados al fondo de la caja -- el destornillador no cabe. Se puede quitar la chapa a la que van montados los ventiladores, pero eso es también molesto -- hay 2 tornillos por lado, mas tornillos que unen la chapa a la carcasa, que hay que sacar desde arriba con un destornillador largo. No es un problema fatal, pero no es la caja que compraría para algo crítico. Aquí es casi imposible reemplazar ventiladores a la marcha, hay que apagarlo todo y desmontar y lleva tiempo. La cosa mejoraría mucho cambiando los tornillos de ventiladores por unos de cabeza hexagonal, sería mucho mas fácil quitarlos sin desmontar todo.
