Firstly, this is my first time working with a M-atx case (Ga-a320m-s2h with GTX 1060 3gb single fan).

A nice and tidy case. Looks great on my desk and seems to be decently built. The front panel especially looks good and would go well with an RGB fan. Definitely a tight fit when it comes to installing the GPU and my wireless/bluetooth PCI-E adapter, but it's manageable. Great that you can remove the drive cage to give yourself more space for cable management. Would have been nice if the case expansion slots were ones that you could put back on, rather than having to make a permanent decision.

Would have been nice if the case expansion slots were ones that you could put back on, rather than having to make a permanent decision. Be careful not to bend the case when removing these slots. In terms of airflow, can't comment quite just yet. I've got a bunch of Arctic P12s coming which will suit better than the 3pin F12s I'm currently using. One thing to bear in mind when building, lie the case down on its cable management side when you go to remove the glass panel. I found it difficult to put on when the case is standing upright without having to put your hand up against it, leaving fingerprint marks. Both sides come with screws that stay attached to the panel.

Overall, happy with the purchase. Bit of a punt since there are a lack of reviews on this case. At this stage, would buy again.

Good case for the price, construction is not too bad but you can tell its built to a price. Panel where rear fan and motherboard sit are very weak so dont apply too much pressure when installing things. Othewise very easy to work with and all cables are marked clearly too. Good for a budget build! Good case for the price, construction is not too bad but you can tell its built to a price.

The Cooler Master Masterbox MB400L is a fantastic MATX case for the price. Cooler Master have always made decent products and in my experience I have never had one fail me as an IT Technician.

I’ve used the MB400L multiple times for various builds for customers over the past months and quite frankly, it’s shocking that its priced so cheap considering it has all the bells and whistles you need.

Inside the box, Cooler Master provides a small tool kit that contains 2.5” SSD/Hard drive mounts for the back of the computer. They also provide a reasonable amount of cable ties for excellent cable management.

Aesthetically, this case is an excellent choice for a semi-professional/Business/Productivity PC. I’ve used the case for clients who have a home office and like to game on their down time and have got great feedback. Functionally, the case has a fan mount at the top with a magnetic dust filter, a rear fan mount and two front fan mounts.

Not sure why you are still reading till the end of this, when you should spend your time buying this excellent case.

Pros: Cheap, Good Quality, Lots of space to house components. Looks great.

Cons: Not finding it sooner.

It has a 2 x 3.5inch disk cages, disks have that slide in mount thing, which is nice, but you can fit a disk on top of the disk cage too, there are brackets for screws. So 3 disks...
The glass panel has holes for screws, if you tighten it too much the glass can crack, though I didn't tighten it too much, and I didn't use a screwdriver to screw it in, it did get a hairline crack around the screw hole. It is better if a case doesn't rely on screws through brittle glass.
There is a different version of this case without the glass panel.

There is a different version of this case without the glass panel.
If your motherboard has sata connections close to the edge where the metal PSU cover meets the motherboard, you might find it tough to remove a sata cable once installed because there is no space left to press in the sata release.
Use the sata connections further away from the metal cover.
Cable management is surprisingly easy, the cables are the correct length re front panel connections.
The magnetic top dust filter appears to be ineffective, though I am pulling air in to blow over the RAM. I think it was designed as an outlet.
The PCI slot covers are tough to get out once the motherboard is installed, so best to pull them out beforehand.
Case can handle a normal average sized PSU.
Price is reasonable

Very happy with the product, just bummed the sales guy at PB tech said it was the best price and wouldn’t be on special any time soon. It went on special the next day. So would recommend keeping an eye out for the deals. Very happy with the product, just bummed the sales guy at PB tech said it was the best price and wouldn’t be on special any time soon.

Overall a nice looking case with a good amount of room for building in. Cable management is a little bit hard with limited space behind the motherboard tray, and limited space in the power supply shroud when using the 5.25 drive bay. Looks awesome with some rgb, and has good space for radiators if needed.

Definitely great value for money. Overall a nice looking case with a good amount of room for building in.
