DEEPCOOL Matrexx 55 PC Case Review

deepcool matrexx 55

The DEEPCOOL Matrexx 55 PC case has now been on the market for some time. The range offers builders a little bit of everything for an affordable price. We have the base model (the non-ADD-RGB) as this option would offer budget builders the best value, without compromising on aesthetics too much.

DEEPCOOL already has some interesting cooling accessories and other cases available that have grabbed the community’s attention but can they really compete with the big boys?

The Matrexx 55 features two tempered glass panels and a lighting strip down the front, making this look quite impressive despite its budget price tag. For some reason, the base model doesn’t feature a PSU shroud, whereas the slightly dearer ADD-RGB model does and you are going to need to buy at least one case fan unless you get the overpriced triple fan version. Performance-wise for what you would be building in this, it’s fine but you are always going to have poor cooling with that tempered glass at the front when compared to a mesh front panel.

Let’s take a closer look at this PC case and see how the different buying options stand against the competition.

  • Good cooling support
  • Two tempered glass panels
  • Two dust filters

The Outside

Our model is the all-black version of the Matrexx 55 and first impressions when you unbox this is quite pleasant. The front is three quarters tempered glass with the far right side being plastic and separated by the RGB vein running the length of the front panel. Branding is fairly obvious although kept to a minimum, with just the one DEEPCOOL Logo situated towards the bottom.



The back is fairly standard, with a PSU cutout at the bottom and seven expansion slots just above. There is a vent for a 120mm fan to be mounted at the back and there is a bit of wiggle room as to where you can position the fan, optimizing your airflow setup.



Everything was as expected at the rear but what is often rather disappointing with some budget cases is the use of these snap off steel expansion covers rather than replaceable ones. Once these slot covers are off, they are never going back on and if you change your system around or move from a Wi-Fi card to wired, for example, you are going to have a hole at the back.

The Side

At the interior side, you get a full tempered glass panel that is screwed into place by four easy to use thumbscrews. Once the screws are removed there is only a small amount of rubber holding the glass in place, so take care when removing. Towards the front is ventilation on either side, which is to compensate for the tempered glass front. The first thing to say is, this will draw air in and most builders out there will have adequately cooled components, but beware, a setup like this always brings higher temps than an open front.


The tempered glass panel looks great and makes this budget case stand head and shoulders above others such as the Thermaltake’s H15 but it would have been great to see a touch of tint around the edges just so you can see through the bottom. Small gripe though.

The back side panel is just a sheet of steel with two removable thumbscrews towards the rear.

The Top

The top is where we see the front I/O and a handy included magnetic dust filter. The dust filter is something that I often take for granted and I’m very happy to see these included in budget builds, as they don’t cost a lot to make.

The top looks a bit cheap if I’m honest and the front panel I/O isn’t the best but for a budget case it is hardly an area of concern. The one saving grace is that the illuminated power button is relatively nice looking and has a satisfying press.

The I/O consists of:

  • Power Button
  • Reset Button
  • RGB Button
  • Audio Jack
  • Mic Jack
  • 2 x USB 2.0
  • 1 x USB 3.0


The available connections are not surprising for a case like this, you aren’t going to be seeing USB 3.0 Type-C on these just yet. Furthermore, this is a fair amount of front panel connectivity on a budget and would go well with most budget builds I’m sure.

The Inside

The inside is spacious and the brand advertises motherboard support up to E-ATX, which is fair enough, but I can assure you that it will be rather cramped in there.

Of course, our model here is the base and doesn’t feature a PSU shroud, which used to be quite typical of budget cases of old. This is a shame, as I have seen plenty at a similar price point that have included a shroud and when you consider that a budget builder is probably going to be using a non-modular PSU, you want to keep things as clean as possible. That being said, a little cable management, and I was quite happy with my end results.


The first thing you notice is the strangely shaped cable cutouts and lack of grommets. No grommets are hardly a surprise when dealing with a budget case but I have never built in something with square cable cutouts before.

The cutout points could have been placed better and they ultimately made cable management tricker and overall the case seemed to work against the goal of a clean-looking build.

The interior is generous but ideally, you are going to want an ATX board inside. With ATX, you can use the cutout holes that an E-ATX will block. If you plan on using an mATX or ITX board, you are going to have a lot of cables on show, and your build will not look very clean, even if you are a cable management wizard.

The front can accommodate a radiator up to 360mm in size. That also translates to being able to fit three 140/120mm fans at the front too. Elsewhere you can install a radiator up to 280mm at the top or a 120mm at the back, with there being room for two 140/120mm fans on the top and a single 120mm fan at the back. So overall, pretty good cooling options on offer here.


In terms of clearance, you can have a CPU cooler with a max height of 168mm and a GPU as long as 370mm. The bottom will house ATX PSUs with a max length of 170mm due to the installed HDD cage.

The Back Panel

The first thing to note at the back is the tiny hole for PSU cables to come through. While this can be a pain during the building process, it does a good job of hiding a little bit more than your average case, which is important due to the lack of a PSU shroud. Other than that, it is fairly standard at the back here, and a great feature is the abundance of tie points dotted around, giving you plenty of options for cable management. There is 23mm of space to manage with, which I found to be more than enough, even with four fans and an AIO cooler thrown in for good measure.


Here at the back is where you can access your HDD drive bay. There are two caddies screwed in place upon which you can install two 2.5 or 3.5” drives. There are spots to mount your drives from the inside on the back panel but they share the same cutouts as your front panel and PSU cables, so it was a no-go from me.


Being a budget case, there aren’t a lot of features to talk about that we haven’t already mentioned, so let’s take a look.

Aesthetics – The case is visually appealing, thanks to its two tempered glass panels at the front and side. Quite a lot of competitor cases are thin metal boxes, with little going for them in the looks department. Of course, the Matrexx 55 has sacrificed some cooling potential but with the right components inside, you are unlikely to notice.

Cooling – The spacious nature to the DEEPCOOL Matrexx 55 means it can live up to the brand’s name and actually offer good cooling support. However, with no included fans this may only be worth going for if you already have the components to take advantage of this.


The range from DEEPCOOL comes with varied features as the price increases. We see the next one up that is closely priced to our model offering addressable RGB and a PSU shroud but still no fans. For the model that includes fans, you are going to end up paying an extra $30+, which isn’t massively expensive but the price is then closer to premium-brand mid-tower offerings.

Our Verdict

DEEPCOOL’s cases have been improving since they started out and this continues. We now see a mesh version of the Matrexx 55 being released and the refreshed base model now features the all-important PSU shroud.

We are reviewing this case though, not the company’s ability to improve, and overall you get a great budget case, with plenty of room inside for ambitious builds and enough space at the back to keep those cables tidy.

The more pressing matter of the Molex connector being used for the ADD-RGB model is a large concern though, as this technology should now be abolished! The included dust filters at the top and bottom(for the PSU) are a great touch and the tempered glass really does look superb.

This base model offers builders on a budget who already own case fans an affordable option that doesn’t compromise on aesthetics. If you don’t have fans, you are going to want to grab at least one for exhaust with this case but with that tempered glass front looking empty, you’d have to ask, what would be the point?

The bottom line is, you should certainly go for the ADD-RGB version as the PSU shroud makes a big difference in the looks department. I don’t see where the triple fan version fits into anyone’s equation though, seeing as it closely matches the Phanteks P400, Fractal Design Meshify C and NZXT H510 for price and they are all much better quality.
