Lian Li DAN Cases A3-mATX case at a Glance:

  • Stylish Micro-ATX case designed by Daniel Hansen of DAN Cases
  • Steel mesh panels located on top and sides providing ample access to fresh air
  • Install the latest modern gaming hardware thanks to the 26.3L internal capacity
  • Highly configurable internal layout to accommodate the latest components
  • Maintain optimum thermals with up to ten 120mm fans
  • Supports ATX, SFX, SFX-L, and Lian Li Edge PSUs

A Small Powerhouse

The Lian Li DAN Cases A3-mATX case is the perfect choice for the gamer who wants a powerful gaming PC but doesn’t have much room. The chassis features a small form factor, standing at just 321.5mm tall or 306mm with the feet removed, 194mm wide, and 443mm deep. The internal capacity, however, seemingly defies the compact size of this case, with a massive 26.3L chamber. Thanks to this, you can install a wide range of modern gaming hardware, such as an Intel 14th Gen CPU or NVIDIA 40 Series GPU. What’s more, this case is compatible with a variety of motherboards, as it supports both Mini-ITX and Micro-ATX models.

Adjustable for Better Compatibility

The internal layout of the Lian Li DAN Cases A3-mATX is highly customisable, with multiple layouts to choose from. This flexibility provides you with options when it comes to your component choices.

The power supply is one of the main factors that will define the layout. The A3-mATX can facilitate several form factors of PSU up to 220mm long, including SFX, SFX-L, ATX and even Lian Li’s innovative Edge power supplies. In addition to this, the Lian Li DAN Cases A3-mATX has two locations to mount the power supply, either in the front of the case, or at the side. Moreover, these two locations each have five points for mounting your PSU, allowing you to change their elevation, depending on which model you choose.

The drive tray can be moved in accordance with where you place the PSU, maintaining the same amount of drive compatibility in any layout. If you position the PSU at the front of the case, then the drive tray can be mounted to the side. Alternatively, if you side mount your PSU, the drive tray can be located at the front of the case. This drive tray has space for up to two 2.5" SSDs, and there is secondary support for either a 2.5" SSD or 3.5" HDD at the bottom of the case.

Performance Cooling

Keeping your hardware cool is simple with the Lian Li DAN Cases A3-mATX. This chassis utilises highly porous steel mesh for both side panels alongside the top, providing ample access to fresh air. Furthermore, with ten 120mm fan mounting points, you can create the perfect airflow to maintain optimum temperatures, even during the most epic of gaming sessions. These fans can be distributed throughout the case with the following layout, three fans at the top, three on the side, three in the bottom, and a single fan mounted to the rear.

Alongside this, you can install a wide selection of CPU coolers. With 165mm of clearance, large tower air coolers can easily be facilitated by the A3-mATX. Furthermore, water cooling is an option as this chassis has three locations for mounting a radiator. The top, side and bottom of this case can all support a 360mm radiator, with both the top and side supporting either a push or pull configuration, while the bottom supports a push layout with the fans mounted on the underside of the radiator.

Ohhhh Yes, what else is there to say

by Sean Alessi star star star star star

For a long time ive been wondering why mATX cases were so big, up until now I was using a Corsair 2500X case which I thought was huge for an mATX case, and even considered just moving to ITX instead, I had been debating the Lian Li A3 for a while now, wondering if I could fit everything I wanted in it, and after watching and reading many reviews on it I decided to bite the bullet, at the price point it wouldnt of been such a hard loss if I couldnt get in it what I wanted, however, that wasnt the case. It was a bit tricky to get everything to fit and you really have to think about where (above all things) you are going to mount the PSU and how you are going to mount it, I removed the PSU and GPU from my old build to work this out before stripping everything else out of my old system, I ended up using the SSD bracket at the front of the case and using the SFX-L to ATX bracket to mount it with the supplied stand-off's to the SSD bracket, this allowed me to then mount my pump res combo to the other side of the SSD bracket, overall this was about an hour and a half of work, once I knew these 3 parts would fit, the rest was easy, you just have to remember to fit things in a certain order, so for me it was motherboard, then any wiring required at the top of the board before fitting my radiator and fans as this then blocks any access to to top ports of the board, its the same situation for the bottom end of the board, make sure you wire everything up before fitting any fans and GPU in the bottom end of the case. Overall, im over the moon with this case, such a small footprint for such a large system and half the size of anything ive owed before, thank you Lian Li and OCuk: https://imgur.com/kVt8KtH


Great but Hard work, not quite as compatible as it suggests

by Dave star_border star star star star

Using this case with a ITX mobo and sfx. Psu at the front, wires don’t reach. 1 of the ways to fit the psu that would help with the wire length of sfx is atx psu only…. Barely any width fitting a 360mm aio. Aio fans are squished right upto the ram sticks. Apart from that the case is awesome, plenty of gpu clearance, have a 4070 with t30s fans in the bottom and still a finger gap between the fans and gpu. Highly recommended, custom cables are needed for a tidy job if using sfx psu but it’s workable without. Psu can only be fitted to the side if using six cables.
