Great case at an amazing price
I bought this case for my recent gaming computer build and I’m very impressed. If has more than sufficient cooling straight out of the box and gets great air flow. The front grill is great looking with its sleek side and glass viewing panel. The cable management is superb as well, hiding everything perfect behind the back wall. The case feels very rigid overall and has enough space for the larger graphics cards you can currently buy. It’s not just about the form factor with this case but the functionality too. I highly recommend getting this if it’s compatible with your mother board.

Good case for the price
This case looks clean and premium. Cable management is good, airflow is amazing with room for a ton of fans and a 360 AIO on top. Itâs future-ready too, with support for reverse motherboards and big GPUs. Get this case if you care about aesthetics and smart layout. You can basically modify this case to your own

My favorite case I’ve encountered so far
Absolutely the best case in which I have built. Everything was thought out and designed well; stuff just made sense. Lots of space for managing thick cables. Pack it full of fans, and it has violent airflow. It’s not flimsy at all, and looking amazing.

Great case!
Wonderful case. The modular design accommodates a very wide range of standard PC motherboard designs, horizontal or vertical GPU mounting (riser cable NOT included however) and a variety of fan, cooler and radiator arrangements. The case is well-built, easy to configure and assemble your computer inside, and very sturdy once finished and buttoned up. Very quiet in operation even with a number of fans installed and running at good speeds. Extremely happy with this purchase.

King of Modularity… Now lets see if they actually make custom parts for it..
Due to a shipping issue I ended up with two of these cases in white and long story short it was decided I could keep the second. Being a hobbyist PC builder I decided to use the second one for another build and really have to say, as someone that likes to swap parts around, having two builds using this case- the modularity makes this case by far and away the BEST case to use if you want to swap stuff around. There are some odd things about the it though. I would have liked to see a dust filter for the top panel and really my biggest gripe is lack of instructions. The vertical mounted GPU capability is super nice but until i saw a video explaining it how to mount it, it felt super flimsy. Overall I think Corsair knocked it out of the park.. Keeping in mind I basically paid half price and my experience is from being able to build in 2 of them at once. That being said, the fact you can easily break this case down to its bare bones (once you know how) makes it a breeze to build with.

Great case! Worth $100.
Build quality is iffy, feels not so solid metal, my glass came in scratched a bit, reguardless, fantastic case, amazing cooling, and insane amount of room for building.

Great case for your next build
Great spacious case good for a first build, very roomy for extra fans, and large gpu. Has good cable management options, comes with velcro and zip ties for cable management.

Great unit to work with
Used this case with a BTF build (MSI Project Zero) and it was a pleasure to work within. Easy to move trays and items around, airflow was functional and temperature internals was really solid. The case itself is sturdier than you’d expect for the number of BTF options (MATX, ATX) but really held up. Cable management through inbuilt velcro is very solid.

Devo dire che ho già una lunga esperienza con Corsair, sia per quanto riguarda i case che altri componenti quali PSU, ventole e periferiche varie, quindi sono andato abbastanza sul sicuro. Non mi aspettavo comunque di essere così soddisfatto dal risultato finale. Un case ampio, robusto e assurdamente modulare.Se solitamente avete difficoltà nella fase di assemblaggio o siete alle prime armi, potete stare tranquilli che non avrete problemi. Ho smontato ogni singolo pannello per avere spazio di manovra e infine ho rimontato tutto facilmente. Si ha l’impressione di star lavorando con un prodotto premium dal prezzo nella norma (soprattutto per l’offerta del prime day).Non mi è piaciuto il posizionamento del pannello I/O così in basso, in quanto io, per motivi di spazio, posiziono sempre il PC sul pavimento. Questo costringe l’acquisto di una prolunga USB, in modo da non essere costretti a poggiare i dispositivi per terra.Le tre ventole RGB sono un’aggiunta carina per chi è interessato anche al lato prettamente estetico della propria build, ma anche essenziale per l’airflow. Ho aggiunto una terza ventola nella parte posteriore e le temperature sono perfette.

Great case! Easy to install as all panels are easy to remove. Good space for cables. Nice and quiet fans. Runs cool.Only thing is that the front panel is in the bottom and this is a bit annoying if you keep your PC on the floor. But this is not enough to rob a star. Great and good looking case!

Un des meilleurs boitier actuellement sur le marché, technologie mesh a l’avant, qui permet d’obtenir un excellent airflow, sans trop de poussière, grande chambre côté câble management, qui permet de faire des branchements propres, ventilateur pré monté très silencieux et avec un très bel effet RGB,Possibilité de monter jusqu’au plus grand watercooling du marchéLa structure est très solide (pratiquement aucun plastique) et le boîtier est très spacieux, pas de problème pour le montage de votre config, et la question de savoir si ça carte graphique passe ne se pose même pas, elle passeEn bref, je recommande ce boîtier haut de gamme, qui propose un bon rapport qualité/prix et de très belle finitions, il ne fera pas tâche dans vos setup les plus beaux.

This case is amazing value for money and includes everything needed to get setup.The quality of the case feels premium and looks great. The black case fits in any setup. Cable management is easy with the included ties and thought out routing.The front three fans can get quite loud but they keep the PC cool and look great.If you are building a PC for the first time – I highly recommend you consider this.
