Cooler Master MasterBox MB511 ATX Mid-Tower with Front Mesh Ventilation, Front Side Red Accent Mesh Intake & Transparent Acrylic Side Panel

Pros: - The front mesh allows for way better air flow vs its counter part MasterCase H500P.

- Edge to edge transparent side looks real good. It is actually glass/acrylic, not some cheap plastic.

- Fairly easy to build into. Plenty of places to tuck cables and or clip them to a side. All the edges within the case are dulled and cruved-ish.

- Has a lot of support for different radiators and configurations. I could have my choice of putting my 240mm rad at the top or the front. Front can take up to a 360mm rad.

- Nice power button and front panel design.

- Removable fan filters for top and bottom vents. Top is magnetic. Bottom is clip based.

- Bottom mounted PSU with a shroud.

Cons: - A bit on the heavy side. Construction is mostly steel/plastic as with most cases. Would've been nice to see some aluminum for a lighter weight, but I guess for the price, it is okay.

- While the mesh design does allow for way better airflow and thermals, it will produce more visible dust collection on the outside mesh.

- One bundled fan? Cooler Master cheaping out in this department. :\

- Limited 3.5" HDD space. Only 2 slots.

Overall Review: Overall a decent case. Currently using it as a Ryzen 7 build. MSI X370 Gaming Pro. Corsair RM750 and a Corsair CPU water loop.
Everything fits very well.

Pros: + Very high airflow case compared to my previous case that was $20 more in price.
+ Plenty of intake air mesh to prevent only large dust particles or hair from entering the case.
+ Plenty of storage drive bays and mounts for a compact mid-tower case.
+ Thumb screws for both side panels make everything extremely accessible.
+ Good at keeping components and case cool if you have good fans.

Cons: - Poor scratch resistance of the transparent side panel.
- Poor quality mesh and filters on all sides of the case.
- Very fine dust and particulates penetrated the case easily.
- Very crowded PSU shroud when at maximum storage.
- Bad routing hole cut out location for the SATA cables.

Overall Review: The biggest DISSAPPOINT was the plastic display window. Unlike tempered glass which is usually resistant to light scratches, the plastic display window had a very visible scratch. This was how it was out of the box and was located on the side where there was no protective plastic film. Also things like lint, fibers and hairs that make it through the mesh sticks to the plastic display window often.

Supplied when you open the box are the instructions and warranty. The provided instructions were very unclear at first because it was just pictures, arrows and a menu of screw graphics with letter designations to guide you through the installation process. During installation the front panel pops out very easily with very little force if held from the front, so you had to carefully move the case.

There was plenty of storage bays for this case but due to how compact this case is installation of my storage devices was difficult because of how little room was in the PSU shroud. I was able to fit two HDDs and three SSDs into two provided combo 3.5”/2.5” drive bay and one SSD drive bay at the back side of the case, this created an extremely crowded situation that made cable management very difficult due to the amount of SATA and power cables needed for all that storage.

To make cable management worse, a normal sized PSU (Corsair AX 860i) was difficult to manage in the PSU shroud because of how little room there was between the PSU and the hard drive bays. Even with the best cable management and tucking/hiding, the area between the PSU and drive bays became a bird’s nest of wires.

There were plenty of holes and cutouts to route all your cables but routing wires for the SATA drives was very poorly designed. The cutout closest to the SATA ports is very far from the SATA ports on the motherboard making L-shaped SATA plugs impossible to use and forcing you to use straight plug SATA cables. You can check the product website for pictures of what exactly I’m talking about. I felt like they were trying to line up all the routing cut outs vertically but didn’t account for the SATA port area.

The amount of mesh on this case made air flow in and out very easily making it the most attractive feature for me. The design and quality of the mesh was a different story though. The outside mesh that meets the intake of the power supply unit is basically just a piece of rectangular mesh held in by a few tabs. The top mesh filter is magnetic but very weak and prone to move if touched. The red accent and bottom filter of the front panel were removable for cleaning, but the rest of the front mesh wasn’t. It left me scratching my head why only some of the mesh was removable for cleaning, but the rest of the mesh front wasn’t.

The front and top fan/radiator options was vast for this case, but I found out the hard way not to mix case fan sizes for the front intake for this case because you would end up with a large amount of empty space between them. I have one 120mm and 140mm fan installed at the front but due to the holes in the front for installation there is a huge gap between the two fans. Depending on how tall your DRAM sticks are, you can be limited on how thick your radiator and fan set up could be. It's making me reconsider ordered a 240mm radiator set up because of it since I want to keep the front radiator purely fans.

Overall, this case is a very good entry level budget case when compared to other cases in this price range. I use this case for gaming and at full load and extremely aggressive cooling plans for my AIO radiator and fans, the case’s impressive airflow keeps everything at good temperatures. The quality and design leave many things to be desired and if you want to avoid most of the problems you will meet in this case I recommend you invest in a premium case with more features and room.
