    As soon as I saw this case, I immediately fell in love and realized that I would choose it for my new assembly. But at that time they were out of stock in all stores. After almost a month of empty wandering around ebay, the cases finally appeared in stores again and I immediately ordered it. The composition of the system is as follows: MP - Asus B450M TUF Pro gaming CPU - AMD Ryzen 5 2600 (exactly without K, since it is cheaper and even slightly more profitable in overclocking) RAM - 2x8…

    • Great look. Simultaneously simple and stylish. Harmoniously fit into the interior. Great opportunities for modding. Good ventilation. Compactness and the possibility of horizontal placement.
    • Everyone says that the transparent plastic cover is strongly scratched. Haven't scratched it yet, but obviously people are right - it's not tempered glass. The wires are short. In my setup (the location of some connectors on the motherboard and just such an orientation of the case panel with buttons), the USB 3.0 wire barely reached straight, tight and tight. For me, 1 slot for 3.5 HDD is not enough, but I decided that I would get by, this is a solvable problem.

    Excellent quality, absolutely not expected for such a price.

    I was looking for a compact, ventilated case for a long 300mm card. This option is very normal. Rigid construction. The metal is thick. I did not bother about the fans. Until I saw how much 140mm coolers cost. As a result, calmly you need to add 1500 to the cost of the case. So it becomes not so budgetary.

    • look solid, Removable magnetic mesh. Very comfortably. The ability to rearrange the control panel to any face. Possibility to install the case vertically and horizontally.
    • 1 fan is not enough. If you buy more, it turns out not so budget. I would like 1 more space for a 3.5 disk. Plugs for the video card break out hard I would like not acrylic, but glass.

    Good product, good quality, not bad.

    In general, the case is very good, I'm glad I took it. The price is very reasonable. But the fact that there are no holes for 140 coolers on top is sad. (If this minus were not there, I would call it ideal, at least for me. The best ratio of quality, functionality and price.

    • - The case is beautiful, there is a nice glass cover. - Well ventilated due to perforation over the entire area. - It is possible to make an unusual layout, at least turn it upside down, or on its side. - There is a 120 cooler in the kit (but I immediately removed it). - Two anti-dust nets on magnets and one on the bottom, attached with rubber buttons - There is a very spacious place for wires under the back cover, you can also install three disks there (2 small ssd and 1 large hdd). - Slots for switching wires. - Included a bunch of bolts and good miniature ties And in general it is very thoughtful, everything is convenient.
    • - Pretty thin iron. You twist the bolt and you can see how the body flexes. Such a thing, it's scary to crumple. Hold very well from the back. - All holes marked for coolers are smaller than the standard cooler bolt. It will not work to screw it in by force, you need to pick them up with something, you did it with a knife. Despite the fact that the iron is soft and thin, this is done easily. - The biggest downside! On the front panel there are holes for coolers 120 and 140, and on the top only for 120. I don’t understand what prevented me from doing it too. This is of course a wild bummer. The 140 is significantly quieter than the 120, the revs are lower, and the traction is good. I had to return two coolers 140 to the magician, exchange them for 120. Although you can make a farm and somehow drill them yourself, but I didn’t want to spoil the new case, it’s a pity.

    I'm satisfied, the product is exactly as described.

    The case is good for its money, BUT it faced such a problem rather because of its not deliberate actions; I collected everything, stuck the video card Aorus GeForce GTX 1060, we note that its length is 280mm and TDP 120 watts, everything is at a great temperature and the noise is normal. Then I upgraded to MSI GeForce RTX 3070 VENTUS 3X OC and then the fun began. Its TDP is 220W and its length is 305mm. In general, now this box heats the room better than the battery)) Setting up the coolers did

    • Compactness, price, convenient location of the case in 2 planes
    • The slot for the HDD is clearly superfluous, especially on the back wall where there are a bunch of wires and 0 air flow, respectively, will boil. Regular cooler for ejection, there is little sense from it.

    Everything is already well painted, I will answer the question that I had before buying. Will a 240mm radiator fit into the top cover. The answer is that it will fit with a file. Initially, there was a desire to put the cooling radiator exactly horizontally, because. warm air rises. The manufacturer does not indicate the possibility of installing it in the top cover, only in the front. That is, you must either turn the polarity of the fans to blow forward, or warm air will go into the case. So,

    • Cheap, with a window, compact, filters.
    • There is no handle included and it is not clear where to buy. In the pictures there is with her, there are holes for her, but the handle was regretted.

    Bought for a compact system. there were no questions with the connection of the kit, a huge 1080ti fit in. Access to connect I was struck by the processor power supply, there is a lot of space (apparently it is calculated that 280 dropsy can fit on top). It is convenient to turn on and off, the position of the body is also recumbent and standing. It is not necessary to reach for the on button if the case is on top. The racks under the motherboard did not go very well, well, this is the norm for

    • -Compact dimensions. -Amount of space inside. -Complete set + appearance. - Removable frame for fastening the PSU -Plenty of space for cable management - Dust collectors throughout the body on magnets
    • -Dirty plastic instead of glass -Flimsy panel on-off case.

    The product is really good, I'm glad I bought it.

    good case in its class and for the money but it's better to take the version with tempered glass (well, this probably applies to all transparent covers) Has pros: compact, perfectly blown, there is a place for cable management and of course it looks cool, and if you make a backlight . Has cons: the wires on the control panel are a little short, the plexiglass side cover is scratched very easily

    The best purchase in my life, I will definitely buy it again.

    Roomy, deep compact case, be queite dark rock 4 fan installed without any problems, Asus z390m-wi-fi motherboard, i7 9700k processor, ssd 970 Evo plus 500 gb. Outwardly, it looks great, there were no problems with the installation of equipment, a lot of space for additional equipment! I recommend to buy.

    • roomy compact body
    • discharge case fan

    Nice price, good quality.

    Good body for the money. If you are satisfied with these points, which I indicated in the shortcomings, then the case can be safely ordered.

    • Enough space for cable management. Sold. Compat.
    • Acrylic glass. Only 1 slot for hhd. Open power supply (no baffle).

    The product suited me, I will recommend it to my friends.

    Cool case, fully met expectations, the kit included a fan, a bunch of screws and clamps. Everything is good except for the softness or thinness of the metal.

    • A beautiful case, compact, roomy, the presence of removable dust filters, the lower location of the PSU, glass on the panel, control, lightness.
    • Very soft metal. When you press the power button, it bends slightly

    Has some pros: Very flexible in terms of location. You can place it even on the bottom wall, even on the top, even on the side. Good cooling due to mesh Cons: A little pricey, but overpaying for the ability to arrange as you like. The downside is that the transparent wall is not made of glass.

    Overall good, but expected more.

    I would give the product a solid four, maybe even five, but I got a copy, along the "glass" of which there is a deep scratch. In principle, the computer stands in such a way that it is not particularly noticeable, and I bought it at a big discount, so I will only leave a bad rating

    • Nice and interesting case. The kit is as complete as possible: there are couplers with a margin, all the bolts are also with a margin. In this respect, well done!
    • Flimsy body. It is made of soft metal, so it flexes when you press the body buttons. I decided to wash and dry the filters on which dust should settle. I washed it, but after a short heating with a hair dryer (really short), one of the filters shrank and curled up. Xs, how to straighten it, I'm trying to do something, but it doesn't really help. Not glass is installed on the side, but really something that scratches very quickly, I barely vacuumed this "glass" with a special nozzle, but it all turned out to be micro-scratched, but still.

    Great quality, happy with it one hundred percent!

    Great compact case that fits most full size components. The fans are well audible due to the perforated case, but it keeps the temperature like on an open bench

    • Compact, stylish, easy to assemble, magnetic dust mesh
    • The complete fan cracks, acrylic glass (Lego gets dirty, scratched)

    Revainrating 5 out of 5

    The quality exceeds all expectations, I recommend to buy.

    I dreamed about it for a month and expectations exceeded reality, it is much more compact and beautiful than in the photo-video. Got pros: Multifunctionality in position, competent arrangement of fasteners for components, dust nets with magnets, compactness, ventilation, design, price. Has some cons: I don’t see any flaws, but the design is possible for an amateur. If you are not satisfied with the format of the mat. micro atx and mini itx boards, you can look at q500l, it is slightly larger…

    I like the product, the quality did not disappoint.

    The airflow here is conditional - although the whole case is perforated, it is better when the front panel is not perforated, but a full-fledged hole with skids for mounting fans, otherwise the front fans have to overcome a lot of static pressure. In general, for such a price, a quite normal mATX case, cable management and space for a 3.5 disk behind the back wall add about 4 cm of width compared to other cases. With the factory location of the button panel, the USB wire cannot be laid nicely…

    • 1) magnetic dust filters 2) cable management 3) a 3.5 disk bay behind the rear wall!
    • 1) short USB cable from the panel 2) plexiglass
