This can be the best market fish bobble case right now. This is a bold statement, I will admit, but I am ready to back it. And okay, I think it’s probably not a great surprise, either, seeing how Lean Lee invented the entire category to start practically.
It’s now legend PC O11 dynamic There is no doubt, one of the most famous chassis of the day when he launched the first time, in which hobbies, journalists and influences were the same. Its bold smoking glass panel design, cheap price point, and impressive compatibility moved the Lian Lee’s position in a really horrific competitive market. And, okay, you will be strictly pressured to go to the PC Part Chooser, and during these pandemic years there will be no construction to make it a champion immediately.
Although proceeded faster in half decades, the ecosystem changed dramatically. Haiti, NZXT, Carser, Thermal Tech, Phantox, and others are now fully jumped on this bandwagen. If you want to keep the Chassis King title, it is not enough to stay with it for years by year, it is not enough that you get a bit of adaptation to it year by year, and the boy is swinging with Lian Lee with O 11 Vision compact.
The compact is actually a repetition update from the initial O11 vision which was launched back in 2023. The big difference between the two is actually Lian Lee with the overall map of this. Surprisingly, in view of the name, it has an internal setting and dimensions have decreased significantly so that the overall range of the item can be substantially reduced. Overall, we have lost 10.4 liters of internal space, and decreased by 32.5 mm on the length of the dimension, 18.1 mm at height, and 16.5 mm on width.

It’s not much like it, but when you look at it, the ETX supports the Mother Boards, full-length GPUs, four radiators, and 11 fans in its full fat mesh cooling mode, this is a seriously impressive cutback.
The real win, though, is the price … this is the nuts. The total cost of writing at the time of writing, or about £ 133 UK is $ 124. It’s amazingly cheap for what you are getting. The corners are cut to make it possible, including the definite reduction of fans, but this price is found in the cost of you, effectively with two running methods (full mood glass or mesh roof), as well as an anti -GPU seg bracket, when 2x 3.5 -inch is a sharp, racing, racing, racing. It has been an uncertainty, it has happened.
On the first inspection, you will see that the matter is incredibly DIY friendly, especially for models. Some pop Riots are keeping things together, but a large part of the chassis is kept in conjunction with the Philips Head screw. Most panels are usually kept with thumbs, or with small screws, and you can completely remove the clean aluminum fossil panel from the front and ceiling.
Its default sequence comes with this mesh top panel solution. Remove this mesh FASCIA, and underneath you will be welcomed by a removable radiator bracket, as well as a support column that anchor on the front glass window. Remove the column, and you can install the added top glass panel that Lian Lee bundled with chassis. It’s extremely fast and easy.
A sharp look at the internal, and you will see an anti -segarte bracket out of one of the rubber cable groommet. It is adjusted and down, though in my case, when I was testing, together with the Asus X870E-E and a considerable extent with the Chinaki Zotek Triple Slot Card, it did not reduce so much to provide any major support.

Side radiator brackets, though … now, this is the work of art.
Cable management in the back section is also considered to be quite thought. Most of this, with Velcro Strip and Tie -off points, there are many rubber gumts (sadly, what’s less common these days). Lean Lee also added a magnetic cable clean door to help you hide the majority of cable dirt, and also has two 2.5 inches SSD, which rotates in a safe position through the magnets placed on both sides. During the construction process, it is very useful to keep it off the path, though you can only remove it from its possession and instead remove it completely. As far as PSU is concerned, it has found a growing back -to -back solution that sticks to 15 mm or more, which honestly does not end the world and gives you a slightly more space for cable management.
In an ideal world I would love to look at some plastic cable channels instead of just Velcro Stops, but it is a very minor pet urine, and once you have removed the 3.5 -inch HDD cage down the bottom, if you wish you want to be there, there is only enough cream cabled.
Side radiator brackets, though … now, this is the work of art. Engineering Genius, which is mostly inactive. This Mother Board is stored internally with the thumb side of the tray. Remove it, and you can fully tilt it to your radiator and fans as well.

What is incredible about this is in fact the opposite. If you are running three 120 mm fans on the floor, you can easily turn yourself to give yourself radiators and fans more space. As an alternative, Lean Lee has also added a back cable gumt, not for cables, but instead of AIO tubes. So you can effectively leave the brackets where it is and instead can run the AIO in the reversal, which points to the back of the tubes, around the side of the bracket, all around the side, out of the grommet, and thus in your CPU. A very unique and strange look, and personally I decided against it in my construction, but it was nice to have this option.
As far as cooling, in vision mode, you have more support for the eight 120 mm fans: three side (I recommend intake), three floors (again intake), and two in the back part (work like your path). Along with the variations of the mesh, you can slap one and three 120 mm fans in the roof (or 2x 140 mm) there as well as the route. It naturally lends itself a positive air flow chassis, and the temperature was relatively solid solid during my time testing, definitely with air pulling air by AIO.
However, there are many glasses here. Don’t expect it to go too cool.
Test Platform:
CPU: AMD Ryzen 99900x | Rum: 64GB (2x32GB) Team Group T-Criter Specialist DDR5 @ 6000 C34 | SSD: 2 TB Main T705 M.2 PCI 5.0 SSD | SSD: 4 TB Main T500 M.2 PCIE 4.0 SSD | GPU: Zotak Jefforus RTX 5090 solid | Mother Board: Asus Rog Strix X870E-E Gaming Wi-Fi | CPU Cooler: Tracks Panorama Argub 360 | Psu: 1500W NZXT C1500 80+ Platinum
It took me about 1.5 1.5 hours to move my system to the O11 vision compact, and also includes a strip out of NZXT’s H9 elite. I am very rare about what I complain about, from the point of view of the system fully. When it comes to this whole method, Lean Lee has really covered all the bases, and doing this is just a wonderful task.
The chassis itself, from the point of view, is extraordinarily clean and, as the name suggests, is also surprisingly compact. Still, this is not without error. I am not sure that the AIO tubes pass Throw is really worth it, and certainly in the form of a non -mesh, there is a huge difference of metal over the Mother Board, which looks like a little barren without anything.

If buy …
✅ ✅ You value the greatest aesthetics: You need clean, glass, fish bobel chassis, and you don’t mind spending a little extra for some fans.
If not buy …
❌ Additional fans are not on your radar: You do not have a budget for extra air cooling, or you are not a big fan of dust and case management.
This is something that is clearly seen by Lean Lee, in all similar advertising materials, a small display has been presented in its construction, which does not conflict with the CPU power pass throw, it will be a good touch. In an ideal world, it would be better for the mother -in -law to move only an inch or two inches. Not only to eliminate this negative place, but also to provide you with the most maternal board connector and three floor intake fans a little more wuggle room.
But, and here the point is, it still floats around $ 120. Despite being a fan of fans or fans (who always feels like a mushy in a case that can support 11 bloody things), what you find for this investment is outstanding. With a very clean design, crazy quantity of versus, and strong cooling, even despite this greenhouse effect, Lian Lee O11 vision compact is nothing if PC Building Arena is not a real champion. Of course, this can be one of the best PC cases, I have experienced in 2025.
