When I put my PC together, it was fairly easy to use the room inside the case, easy to connect all the cables for the fans and LED. It has plenty of room inside, huge case, my 1070 GPU seems like a small card inside. I do love the LED addition, that is why I paid more than the regular case. You can switch colours on it, however it is done by a switch, which I personally placed inside the case, but I am sure you can move it to the outside as well. The switch is roughly the size of a Leatherman (when closed) or smaller a little. I think I would have preferred if CoolerMaster integrated this LED switch into the case on the front, so you can just press the button whenever you want. This is me personally saying it, I am not a fan of a separate switch that you can place wherever you like.The pre-installed fans work great, you have 3 in the front sucking in air and 1 in the back pushing air out. Keeping my case cool, my current set up with a i5 9600k and gtx 1070, the case is around 30-35C inside average under useThe filters are amazing, well thought, maybe not the best, highest quality, but for this money, I am well happy with them. The top is magnetic, clever thought. The bottom is a tad fiddly to put back on, however not difficult. Definitely makes cleaning easier. The front looks fantastic, and you have an additional 2 USB3 ports there.The side window is not tampered glass but acrylic, so it can get damaged easily, but only if you are a clumsy monkey. It looks great, darkened as well so the inside bit is still visible, however creates an expensive look.Overall, I am happy with the design and quality and would recommend to those wanting to spend less than £100 on a case. ### ⭐⭐⭐⭐⭐ Very satisfied with this product. *by F***Z on 5 May 2018* This has got to be one of the best 'bang for the buck' cases out there.For this price you get a tinted tempered glass side panel, 3 RGB fans and enough space for an ATX build.The RGB fans do not have super detailed functionality, but they have several different color switch modes and settings to choose from, making them the perfect 'babies first RGB set' to play around with. (another pro to the RGB is they dont need any software, just wire them to the reset switch and select the mode you like)Pros:-Great and rigid construction. No cheap non-reusable PCIE slots here.-Excellent looks, not a solid box shape-Big enough to house ATX but still very compact in its size-Easy to work inCons:-No front panel dust filter-Has a top dust filter but its basically wasted because no fans use it by default (I configured my case to have fans there)-Thermals can get a bit on the hot side when under load-Default fans can get loud when under load-For looks, the indent where the tempered glass side panel is not big enough, so it sticks out ever so slightly outside of the case (biggest con from a visual perspective)-Reset switch cannot be clicked with your fingers. You have to use some tiny tool like a quetip or a toothpick to click it.-Front fans need to be positioned on the mesh, otherwise the fans are choked.In conclusion this is that this case is an incredible deal for all the features it provides. For the price you get so much (RGB, TG sidepanel, solid build quality). Ofcourse this case is not perfect. As mentioned above its provided default cooling options leave it lacking in a technical aspect, and my biggest gripe with it is the fact that the indent for the sidepanel is not big enough, so the glass sticks out like a sore thumb. If that wasnt a problem, this would be the best case on the market for me, but no case is without its flaws after all. I think that even with all of the cons, this is still a great case and as mentioned, I am very satisfied with it and would reccommend it whole heartedly to anyone.Good job Cooler Master! A spectacular visually appealing case! ### ⭐⭐⭐⭐⭐ Amazing value for what you get *by A***X on 17 September 2019* The MB520 RGB is a well designed case at a great price point.The front of the case has enough gaps with mesh dust filters to allow good intake of air, and 1 rear fan ensures air flow over all the components, and also at stock you have positive air pressure that is good for keeping the dust out of the system.The RGB can be controlled by the included controller that you can link to the Reset Switch and that will change the RGB Mode, or if your motherboard has an RGB header, you can link to this.Plenty of room to work inside. Cable management is easy to get right.This doesn't have some of the problems that other "budget" cases have. No sharp edges, the rivets are painted black, it's a tempered glass side not acrylic.I will list the corners cut that a more expensive case would have - the holes to manage cables do not have rubber flaps, the lack of front USB type C and the "not quite as sturdy" feeling plastic of the front of the case - but I don't think these warrant losing my 5 star review as you can't get anywhere close to this price with a known established branded case with 3 RGB fans and 1 exhaust fan ## Frequently Bought Together - Cooler Master MasterBox MB511 ARGB ATX Mid-Tower with Three 120mm ARGB Fans, Fine Mesh Front Panel, Mesh Side Intakes, Tempered Glass & ARGB Lighting System - Samsung 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
