Whats Included

Cooler Master MasterBox Micro ATX Mini-Tower Case with Magnetic Filters and Adjustable I/O Panel
Owner's manual

Q: How many case fans are included? 1 exhaust and 2 intake?

A: One rear exhaust.

Q: Does this case support all form factors of power supplies?

A: I would say yes. If you're just doing a gaming PC build, the standard atx psu is good. I got a 700w Thermaltake 80+. In hindsight, I probably would have went with a modular PSU for cable management as the case is small.

Q: Does this fit a hyper 212 black edition cpu cooler?

A: Yes, it will.

Q: will this work with a lenovo thinkcentre m series?

A: undefined

Q: Will the case work with the pc parts from a pavilion gaming desktop i5

A: undefined

Q: Will this case will work with dell optiplex 745 computer

A: Good question. That's an older model and I think it's the old fashioned mid-tower desktop. It would be difficult to say without knowing what model your motherboard is inside.

Q: Does this come with a pc fan and how many do fans do it need

A: No, this product does not come with a pc fan.

The acrylic side panel, while appreciated by some, is noted as being acrylic rather than tempered glass.

A great case with a low price and high quality
I am running this case with the included fan, and an additional 120 and 140 mm fan. It is being used with AMD Ryzen 5 5600X and Nvidia RTX 3060 ti. With this setup the cooling is very good and the case is very clean. I love the runs for the cables and the mesh fan filters are very cool. I have seen other reviews saying that the filters reduce cooling performance however I ran tests and did not notice this. The case was shipped in a good box with high quality foam and there were no issues building the computer. I definitely recommend this case for anyone who wants a good quality low cost case as long as you don't mind spending the time optimizing your fans and setup to ensure thermals are good.

Lacking airflow, otherwise good
I purchased this case hoping that it would have good airflow. It, unfortunately, isn't great. I was lucky to not be running many hot-running components (I have a ryzen 5 2600 and a gtx 1050 ti low profile), but if you happen to have a higher end CPU or GPU, I would recommend looking into a different case. On the plus side, there is room for 6 fans, which I took advantage of, but while my temperatures aren't bad, they are certainly somewhat disappointing. That being said, the case is priced quite well and looks quite striking. You can add an RGB strip along the acrylic as there is a small gap, and any RGB fans would also look nice behind the stylized mesh. Speaking of which, the mesh panels are magnetic and can be dusted out. As with any case at this price point, you are going to make sacrifices. It's also quite compact, even for a micro atx case. The side panel is acrylic, not tempered glass. The pci covers are pop-out, so once you take one out, it's bent and can't be installed again. The standoffs aren't installed, and it's quite difficult to do so; it's entirely possible that I made a beginner mistake, but I had to use pliers to twist them on. The power supply also has a pretty strange mounting mechanism, where it doesn't sit in line with the rest of the case, but instead, a good inch or so in the actual case. Overall, it has a lot of great features, especially if you're willing to put up with the drawbacks of a cheaper case, but is strangely lacking in key areas. I recommend purchasing this case if you want a compact micro atx case and you're prepared to spend a pretty penny on a cooling solution.

Budget Case for sure
Definitely a budget case. Everything was going well until I went to install the fans. I couldn't find the holes for the 140mm fans. Allegedly the front of the case supports two. I may have seen where the 120mm fans go but the screws I had were too big. I ended up having to drill them out a bit. The modular i/o panel, for me at least, it fell apart. The plastic piece that pushes the actual power switch fell out and I can't figure out how to put it back together. I do like that the case can be vertical or horizontal. It can pretty much fit anywhere
