  • Absolutely amazing case
Style: MB530P Size: ATX Mid-Tower ARGB
Edit: 10-13-2020- Still using the case, it works great! Note: **You absolutely CAN fit a radiator in the top of the case. ** I have pictures included from my original install that plainly show that it is possible, and even easy. The price has gone up a bit, probably from how popular the case is, but it's well worth it! _______ original review below__________________ I've included screens of my build. Hopefully you can see on the bottom just how "clean" you can make this. I have no external HDDs or SSDs and am using two M.2 drives to make for an extremely quiet build. If you don't read my whole review, be sure to go to the end where I mention something that messed with me for about 2-3 hours that I finally figured out. (A mysterious SATA3 connector.) Going to list off the "pros" of this case: 1. The unobtrusive "cutouts". Cable management is a thing! And they do a great job here on this case. Along the bottom where your MOBO meets the case, there are several small holes that you can hardly see until you buy the thing. If you look at my attached pictures, you can get the idea how I ran the cables up through the bottom and did a quick loop back to plug in items like the HD Audio, USB 2 and in my case, the ARBG cable, etc. 2. Great cutouts on the sides. I expect to get middle cutouts -but these have some nice rubber padding that keeps a minimum of light from showing through. Additionally, they had the perfect set up for hiding the CPU power at the top of the case/mobo as well. (Look closely at the top left to see what I mean...) 3. Airflow. It's hard to get a really good feel for just how much flow is available, but the way they situated the glass panel in the front, and cutouts under the fans as well as on the sides means a TON of air flows through the case. As an added effect, when you look directly at the side of the case, the vents almost GLOW with the color of the fans. I built cases for 20 years and basically poo-poo'd the idea of RGB lighting (or even just plain red or green lights on fans) for years. But about a year ago, I finally got on board, and this case REALLY makes RGB lighting come alive. 4. The fans. Lots of complaints from current buyers for some reason. Again, I have no HDDs, though I do have a radiator. I also have the Asus ROG Strix x470 mobo - and it comes with an automatic fan adjuster (that works with overclocking). I'm running my CPU at a consistent 4000Ghz (about an 8 or 10% overclock) and it runs BELOW room temperature. That's with a coolermaster liquid cooler and this case fans on it. Yes, they stay on and only have one speed, but all things considered, it's super quiet, looks great, and does the job beautifully. 5. The glass panels and the metal panel cover on the back. The glass is legit. It's HEAVY. I've also dropped it, and it's durable. I love the grommets they use - it's the first time I've had glass panels that the screws stayed right inside the panel, and it's got elegant hooks on the bottom that make re-attaching the cover the .. seriously, bar none, and I've been a data center sys admin for 20+ years, and have probably put the covers on literally a thousand servers and desktops - the easiest cover to open, remove and re-attach of ANY PC/Mac/Tablet/Phone, etc etc - that I've ever touched. As for the metal cover - I love how easy it was to attach. I love that when I put the glass panel back on, since the metal is already lining all your cables up, it (again) makes the glass uber easy to put back on the case. (See my attached picture). All those cables (which include PCI-e and power for the MOBO, the fan cables for RBG and power, the case connectors, etc) - all tucked away, nice and neat under that metal panel. 6. Bells and whistles. It's got an extra inch or two of width. Makes fitting in radiators on the top of the case actually a thing. (I had to shop around just to find a case that would do that!) If you read the instructions - and the fact it has its own RGB controller (though it's only a button on the top of the case, so it's rather simplified controls...) that's frickin' cool. USB 2 and 3 (two of each) on the top of the case. I love that the power button has RGB and you can control it. Never, EVER seen a case that let me change the power button color. (Or rotate it along with the rest of the fans, etc). Comes with FOUR fans (One is not RGB, though). Oh, and it's ARGB, if you have a controller (or MOBO) that can take advantage of it. That makes this case REALLY economical. Cons: As someone else mentioned, the area for your power supply is pretty tight. Be sure to test the size of everything first. I'm using a modular 750W PSU, and it fits fine, but I had to plug all my cables that I wanted in first - it just didn't fit/wasn't enough room to try to plug them in after it was tucked in. I originally put my PSU in first, before attaching the modular cables and had to take it back out... Please be sure to look at the advertising material about the case. The pictures that show where your radiator goes are accurate. I used a 240MM radiator on the top and it fits beautifully. (See attached pictures.) It doesn't have a ton of extra screws. That part is true. The instructions are not great. The fact that it ONLY has HDD lights and power switch may throw you for a loop. (I was thankful of this, quite honestly.) There is a connector that came with this thing that REALLY messed with me. It's a SATA3 connector. Just plug it into your power supply. I spent hours looking for what it was supposed to plug into. Other notes (and sorry this got so long! But, I wanted to make sure I put in all the information I could, because this case delivers a TON of value...) Also, the controller cable for the RGB fans included ARE compatible with Asus, Asrock, Gigabyte and MSI. Said controller allows you to use all those manufacturer's motherboards. (One review listed 3 of the 4 above, another person said a motherboard controller couldn't be used at all. Yet, in the bottom row of pictures in Cooler Master's Amazon description (above) in the middle picture you can see the cable right there that allows you to use 4 manufacturer's motherboards.) If you don't have that cable and need it, be sure to return the item and get a version that has the cable. It works great. If you don't have one of the above manufacturers, the button next to the power button works as your RGB controller. (Note: it's not a Reset button. This case only doesn't come with a reset cable or button. Only Power switch and HDD lights. TL;DR: Given that it comes with 4 fans, 3 of them are ARGB, and it's a slightly larger mid-tower that can accommodate a 2 fan radiator (hard to find for less than $150!!) - this is my new favorite case. No, the fans aren't the equivalent of an $80 set, but they're darn close. They are quiet, completely configurable and with all the other bits of hidden engineering (air flow, cut outs, cable management, compatibility with mobo manufacturers, etc) - you get more bang for your buck than nearly any other case. If you check out various review sites regarding this case, you'll see that they agree with me. ;) Nice job, Coolermaster! ... show more

  • Looks great but lacking in quality and accessories
Style: MB530P Size: ATX Mid-Tower ARGB
This review is tough. I didn't want to be too hard on the Masterbox MB530P because it really is a great looking compact mid tower with some nice features. But I do have some issues with it that I think everyone should know about before buying this case. I just did my build in it yesterday afternoon so everything is fresh in my mind. Here are the main points that everyone should know about: 1. There is no question that a huge percentage of the cost of this case is the tempered glass. I say this because the rest of the material quality is severely lacking for a case of this size that cost over $100. With all three tempered glass panels removed it weighs next to nothing and that's because the sheet metal is paper thin. There is also nothing but the absolute bare minimum included in terms of hardware and accessories. In fact I had to use some screws from my previous case to put this build together. Just to give you a comparison, my previous case was a full tower Phanteks Enthoo Pro that cost $10 less than this Cooler Master. Not only is the Phanteks larger and of higher quality overall it also included tons of accessories (custom water cooling brackets, 8 removable HDD trays, SSD brackets, an entire tray of every screw and connector that one could possibly need for PC building, cable management straps, a fan hub and cable extensions, etc). With the Cooler Master you get two HDD trays and only the screws that you actually need to mount a motherboard and 2 HDDs, NOTHING ELSE. It is very bare bones. In my opinion they should have eliminated the back side tempered glass panel and put that money elsewhere. Having glass on the back of the motherboard is unnecessary imo. 2. There is only space for 4 total hard drives (2 HDDs or SSDs and 2 additional SSDs). If you have more storage or anticipate needing more, get another case. 3. As others have previously stated, the location of the HDD cage limits the size of the power supply you can fit in this case. Even with a standard/small PSU you are still going to have a hell of a time getting everything plugged in with the power supply installed. Its not fun. And if you are planning to install HDDs in both slots of the cage, good luck with cable management. Honestly I wouldn't recommend even trying it. 4. The included fans are junk. The three front RGB fans look OK but be warned - if you use the reset button on the case to control the lighting, you do not get full control and cannot even put the fans into a single static color mode! You must use your motherboard ARGB header if you want full control over the fan's RGB, luckily you can do that with Cooler Master's cable (according to the label it is compatible with ASRock, ASUS, and Gigabyte). The on board button only gives you limited control and its not very good. Also, the fans themselves are not very quiet, only run at one speed, and the single non-RGB fan in the back is complete garbage. Just about the cheapest PC fan you will see. Compared to something like Corsair's modern fans, they aren't even in the same universe. I am planning to upgrade to Corsair ML series fans but that is going to cost me more money than the case itself. 5. I don't recommend using a 280mm radiator with this case. Yes they do fit (I have one) but only in one spot. And I really mean ONE spot. Not only will they only fit in front, there is only one position in the front that you can mount it in (at the bottom). It cannot be slid up to the top unless you drill additional holes. I'm not sure why these holes aren't included in the case, there is no reason I can see for them not to be there. You also don't get full airflow through a 280, the openings in the front of the case are only large enough for 120mm fans. In short I wish I had a 360mm radiator instead, it would be a much better fit for this case. 6. The opening in the top of the case doesn't make a lot of sense to me. It is just long enough (front to back) to fit two 140mm fans, which is what I have installed. However, it seems as though Cooler Master made this spot wide enough to also fit a 200mm fan. Because of this, neither option fit exactly. Which means you end up with gaps that will allow air to short circuit into the case. Also, even though technically a 200mm fan would fit, the case does not include mounting holes for a 200mm fan. It doesn't make sense. OK, that about covers the negatives and things that annoyed me as I was assembling this build yesterday. You might be wondering why I gave it 4 stars? Here's why: 1. The case looks absolutely fantastic! Its the only case on the market I could find with three visible 120mm intake fans that also has enough of an opening in front that it won't restrict the airflow. And by the way, the small piece of tempered glass in the front can be removed, it is held in place by four screws. This was a pleasant surprise. Any handy DIYers out there could easily make a mesh piece for the front and eliminate all restrictions but frankly I don't think its necessary. 2. For a mid size case of this size (compact) it has some pretty good options for fan and radiator mounting. Better than others of this size, such as the Corsair Crystal 460X. 3. The mounting solution for SSDs is brilliant and couldn't be any simpler. I love it. 4. With the right fans installed the cooling will be top notch. 5. Did I mention how amazing this case looks... ... show more
