5.0 out of 5 stars Very good looking ITX case
Reviewed in Canada on October 23, 2023

This is a very attractive case and it's well made. Compared to my previous "normal" ITX case, this one is the next level in terms of installation. It will give you trouble and frustration.

3.0 out of 5 stars Tempered expectations
Reviewed in Canada on March 24, 2024
Style: A4-H2O ITX BlackVerified Purchase
Got this case because of all the positive reviews. Good and super compact however a few things hold it back a bit. Its compactness is a gift and a curse that contributes negatively in a few areas. Cable management can be a bit challenge , airflow is pretty limited, the case it’s becomes warm to hot to the touch in situations where your system is under load and lastly because limited airflow the system can get very loud to overcompensate. It’s a good case if you are looking for very compact however I feel the NR200 is a better choice even though it’s slightly bigger. Be sure to watch a few online build guides to set yourself for success you do decide to go for this case.

5.0 out of 5 stars Excellent ITX case, thermals better than expected, this is an amazing ITX case.
Reviewed in the United States on May 25, 2023
Style: A4-H2O ITX BlackVerified Purchase
This is now the best case I have ever owned. Super small, quiet, aesthetically pleasing, well built.

Thermals (and noise - Noctua fans...) are better than you would expect with such a cramped case. This case is also surprisingly quiet. Get custom cables if you can, this will aid with cable management. Modular PSU's are a must with this case, non modular PSU's will not work as there is not enough room for spare cables.

This case replaces my excellent Corsair 250D that is large for a ITX case but has excellent thermals.

This machine is used for gaming on a 2K monitor.

Easy to build as all of the panels are removable.

CPU: Intel Core i5 13600K (not overclocked) never gets above 55-62C (better cable management or custom cables would probably improve this to drop below 60C)
CPU Cooler: NZXT Kraken X52 (long hoses but they fit fine) with 2 Noctua 120mm x 25MM fans pushing out and 1 120mmx15mm slim Noctua fan on the bottom pulling air in. This fan is not mounted as there is not a mount in this spot however, it works fine and does not move at all.
GPU: RTX 4070FE - (not overclocked) Stays at 70C or below. Very quiet.
PSU: 850watt Cooler Master fully modular SFF
2 M.2 drives, no 2.5 SSD, don't need them anymore.

Honestamente estaba aferrado a algo como el fractal design ridge pero como no llega a México me decidí por este y honesta mente es muy bueno considerando que puedes meterle más de 1 ssd no lo dice oficialmente pero donde montas una ssd puedes puedes poner una bahía de 2 y así tienes 1 ssd mas también donde está el orificio para hacer espacio a la grafica puedes insertarlas maximo 2 con presión de nuevo nada de esto es oficial pero es otra manera de hacer todo el espacio eficiente y en se tener más almacenamiento, espero les haya servido (no es mío oficialmente es de un yutubero ingles)

3.0 out of 5 stars Buon case, ma come blocco i cavi?
Reviewed in Italy on February 5, 2024
Style: Computer CaseVerified Purchase
Il case sarebbe ottimo tranne per tre punti:

1) non hai modo di fissare i cavi al case creando problemi nella loro gestione, visto gli spazi limitati.

2) il telaio interno è ti ottima fattura ma i pannelli esterni non sono all'altezza per un case che costa più di 160€.

3) ci sono dei modelli, come quello che ho ricevuto, con il cavo riser troppo lungo.

In conclusione, se volete fare mini itx super compatto con un aio da 240mm non sp se ci sono alternative migliori, ma un NR200P che costa meno della metà è superiore in tutto.

5.0 out of 5 stars Erschreckend klein
Reviewed in Germany on December 28, 2023
Style: Computer CaseVerified Purchase
"Da fehlt doch was" - dachte ich mir, als der Karton durch Amazon zugestellt worden ist.
Nein, das Gehäuse ist einfach KLEIN. Wenn andere von einem Schuhkarton sprachen, lagen sie damit richtig.

Eine kleine Herausforderung (nach der ich gesucht habe, wer will schon einen Tisch füllenden PC mit 12 RGB-Lüftern an allen Seiten).

Verbaut ist ein ASRock B550M AC/itx AM4, ein Ryzen 5-5600 (gekühlt von einem Noctua NH-L9a-AM4), Corsair LPX 32GB DDR4-3600 C16, eine Crucial P5 Plus mit 2 TB und eine Asus ROG Strix RTX 3090 OC 24GB - und die passt tatsächlich auf den Millimeter in dieses Gehäuse! Statt einer 240mm AIO sind oben im Gehäuse zwei Noctua NF-A12x25 PWM chromax.black.swap verbaut.

Zum Vergleich: Ein Razer Core X eGPU Gehäuse ist deutlich größer, im DAN A4 H2O steckt aber der komplette Rechner!

Absolute Kaufempfehlung für alle, die einen Aufpreis für eine kleinere Bauform/Verarbeitung zahlen wollen.
Gerade hinsichtlich Grafikkarten aber auf die Abmessungen achten, es gibt 0 Toleranz - wenige Millimeter zu lang und das Frontpanel schließt nicht mehr.
