Review: ✔ Awesome Little Case! (with a Few Small Flaws) - Having had a larger PC case for a while I thought it was time to move to a smaller option. I liked the look of the BitFenix cases but at around the £50 mark, the CoolerMaster Q300L was just what I was looking for price and design-wise. Being able to choose where the USB and power buttons are placed is a cool idea but if you want to use it at the top (like in my setup - Pic above) you will need a USB extension to run the cable down the back of the case. There's plenty of room for cable management and the build quality is good. I have a full sized HDD at the back and there's also space for two SSD's. Having all the holes means that you don't get much airflow pressure but I haven't had any heat issues with my overclocked AMD 1700X. If you're looking at having your PC on the floor, I woudn't choose this case as it'll most likely be full of dust in a few months. For desktop, I've had it running 4 months with minimal dust although you can see a slight dust ring around the front intake fan. When setting up be careful with any fluff and this will easily get stuck into magnet dust filter mesh. If you do decide to buy the CoolerMaster Q300L, you'll also need to invest in some fans as it only comes with one medium-volume fan. LED fans looks great and I've added three plus used the included fan as a front-intake. Pros ✔ Cool Design ✔ Build Quality + Cable Management ✔ Removable Magnet Dust Filters ✔ Compact Size Cons - Only One Fan Included - Perspex Window Tint Is Very Dark - USB Cables a little short I also upgraded the CPU fan to a Arctic Freezer 7 Pro and there's plenty of horizontal room left. If you're going for a big CPU cooler, you might have to watch out with the clearance. Cheers, Jim!
Review: Mastic cooler case - This case is really good. I use PC part picker and I highly recommend it for beginners but this case is very cheap if you can't afford a very expensive case and I had no issues I'm using it my pre-build as a home server to store all my stuff and so far it's been fine with temperature. What's good about this case? It's very small and compact and easy and it's not that heavy and the filters are easy to change.

### ⭐⭐⭐⭐ Great Value
*by R***D on 12 July 2018*

In terms of features this case was very competitive at this price point, overall I'm impressed with the build quality and features. There aren't many good matx cases at this moment in time and the ones that do exist seem to be budget or really expensive. Pros - Nice aesthetic on dust filter. Loads of room for cable management (Even with non-modular psu's) Can position the front Io wherever you want. Very compact but plenty of building space. Good build quality. Fairly cheap. Fits very large graphics cards. Cons - Slightly scratched on inside acrylic panel. Difficult to get acrylic panel off. Could be more mounting points for ssd's/slim hdd's. Overall an excellent case for the price, looks very modern and a pleasure to build in.
