Deepcool MATREXX 55 ADD-RGB 3F

Powerful and beautiful, this mid-tower case sets your rig apart from the crowd with elegantly clean design, accentuated by two 4 mm tempered glass panels (front and left side), plus three pre-installed RGB fans and a RGB LED strip on the front. The fans and the LED strip featuring addressable RGB can be manually controlled by an RGB button on the top, or controlled by motherboard RGB solution of big brands like ASUS Aura Sync, Gigabyte RGB Fusion, MSI Mystic Light and ASRock Polychrome Sync.

Inside the chassis you'll find ample room for up to E-ATX motherboard, and your other high-end, oversized components. You can build your powerhouse clean and clutter-free thanks to its cleverly designed cable management mechanism, like shroud for bottom-mounted PSU, wide-clearance behind motherboard tray for hiding cables, and dust filters on top, front and bottom. Top-mounted USB ports and audio jacks allow handy access to peripherals.

Is a great case for the Price

Pros: Very great value works very well, nice air flow in the front for a case with tempered glass in font.
Has a nice psu cover

Cons: Can't change the color of the power LED around the power button
Cable management

Other Thoughts: Lets face it this case is very impressively priced for what you get. There are far more expensive cases that don't offer what this case does. Most folks now day what to show off there builds and this case does that without killing your wallet. I have dealt directly with the Deepcool custom service of other issues and they are very willing to help to fix your issues. The cable managment is not the best but it is a closed side so not that big of a deal. I would like to add if you can't afford the high end mb that has the addressable headers like me the deepcool rf and the cf fans are amazing considering the price difference vs quality compared to other company's. i have 3x rf120, 2xrf140 all connected and controlled both speed and rgb buy the msi x470 witch has 2x rgb connectors, but no add-rgb connectors. That being said the button control works just fine to control the 3x pre installed cf120 fans i have 2x of the deepcool pwm fan controllers connected to the mb so all my fans i can control there speed in the mb software. works great in the front alone i have a total of 6 120mm fans 4 or witch are in push pull on a evga 240mm AIO with usb connected rgb cpu heatsink and a evga gtx 1070 video card. Sure if it was in my budget i would love some of the high end cases but at least there is a company like deepcool trying to make a quality product for a fair price. This build has given me a new respect for Deepcool and there products, read there product reviews look at there prices compared to the high end company's if you don't believe me it is a no brainer if your on a budget and want a nice tempered glass front and side case. The only really lame thing about the case is that power button it is always on and blue in a case you can change the color on anything. Also the Add-Rgb fans none of the colors are soild without some kind of breathing i personal would have rather the included fans and controller been rgb addressable kinda sucks unless you want a multi color disco.

This case is not worth the money

Pros: Decent size to fit gpu and radiators

Cons: SSD mounting is inconvenient as well the cut out to put your sata and power cable is not even cut correctly to feed in through so I had to put it in one of HDD trays, Manual and how to set up RGB fans is garbage. It's pointless. Manual also shows you little pictures of the correct screws to use on specific areas like GPU, HDD, SDD, MB and you get a little baggy of screws scattered around not knowing which screws are which since the diagram in manual is pointless.

Other Thoughts: The case is cheap. I honestly feel like returning this case and getting a better one. The glass on the side isn't even flush with case as it sticks out. Cut outs inside case aren't even correct and setting up your RGB Lights following the manual is pointless. It doesn't help.

It Looked Pretty

Pros: The box it came in was of great quality...

Cons: This was the first case in 25 years of building computers I ever hated working with... the case itself is "ok" the lilghting system however is flawed... and when contacting deepcol it didnt get any better... the built in argb stripe was a pretty idea till it was murdered by the "controller"

Other Thoughts: tossed the case after deep cool was completely useless and got my wife a cooler master case and now she is a happy camper and newegg made the mistake about asking me to review this

amazing PC case for budget!

Pros: -awesome looking RGB + easy to use
-airflow works well

-I am used to low budget PC cases and this seems like quite the upgrade for me
especially considering the price

Cons: -The only negative for me is the breakable PCI slot covers.. Then again its not that an issue for me

Other Thoughts: -Unfortunately like some others here i first recieved this case completely recked , but newegg easily and rapidly replaced me with a new one in great condition ! Great customer service as well with Deepcool.

First build case

Pros: Looks really cool. Glad I had the option to manually select RGB since my Motherboard didn’t have the option. Super clean and easy to handle.

Cons: Lots of cords in the back that confused me but that was probably because I’m new to this lol. Figured it out after a few hours

Other Thoughts: First case came completely broken and NEWEGG replaced it very quickly and even covered speedier shipping. Overall very happy with my case for the price!

Case is great for price

Pros: -Tempered glass
-sleeve over power supply
-room for liquid cooled radiator

Cons: -cut outs for cables could have rubber seals
-SSD could be placed better to allow better cable management
-arrived with one RGB fan not working properly: fan works but no RGB lights. disconnected and reconnected multiple ways to try and get it to work

Other Thoughts: would recommend this case for anyone wanting RGB fan lighting and on a budget but just be mindful on parts working
