    • I always buy Cooler Master
Style: Q300L V2 White
I'm currently using Cooler Master's HAF 912 and HAF 922 computer cases from many, many years ago. They're great cases, and my only complaint is that they last too long! I've had three generations of upgrades in these cases and haven't had a need to replace them yet. So, for a new budget build I naturally decided on this brand again. There's many positives at this price point: fantastic ventilation on top, front and bottom; easy to remove and clean top and front magnetic filters; a USB Type-C connection on the front, and; adequate space to cable manage. There's also a few downsides, such as: lack of a PSU tunnel for aesthetics and better airflow to PSU, and; functional side panel design that kind of "falls" off when unscrewed. The magnetic filters also have unfinished edges and tend to catch on things easily, plus they slide around easily, making holding the case a bit difficult. Overall I'm happy with this case and it tends to improve upon many aspects of other cases at this price point. ... show more

    • I LOVE THIS CASE.
Style: Q300L V2 White
Review Image by Matthew Geary
this thing was a joy to work in despite it's size. coming from a Thermaltake case that was wayyy bigger I expected to struggle, but had no issues. Airflow is excellent. depending on how many fans you add it might be a little louder than other cases but that's due to the amazing airflow. my build looks EPIC. I originally wanted the black one as it was cheaper but I'm not regretting it at all. ... show more

Love this tower. First time I've ever built a PC. Size is perfect. Doesn't take up a ton of space. I've only been running the fan that's included and haven't had any issues with cooling, airflow seems sufficient.

    • Roomy case.
Style: Q300L V2 White

So I had the original Q300L which was nice but the downside was the acrylic side panel. The V2 fixes that and you get a tempered glass side panel. You get plenty of room to build in, the max size motherboard you can install is a MATX. Comes with one case fan and you can install a total of 6 fans. The dust filters may block off some of the air flow and depending on your components may increase the temps a bit. One issue I had with the case was the top panel. If you have no fans installed the top panel, it can be easily pushed in and be warped over time since the metal is somewhat thin. ... show more

    • Missing parts, poor airflow, and scratched glass — not worth it
Style: Q300L V2 White
I’ve built plenty of PCs, and this case is one of the most disappointing I’ve worked with. It arrived missing all screws and the manual, so I couldn’t even mount a motherboard. Cooler Master doesn’t send replacements, so the only option is to return it — a huge waste of time. The airflow is awful because the front panel metal blocks most of the fan intake. Even at full speed, fans can’t move enough air, and the system runs hot. The expansion slots in the back are the cheap punch-out style, so once you remove them, you can’t reinstall them. Build quality feels very cheap — thin metal, flimsy panels, and weak magnetic filters that barely stay in place. To make things worse, the tempered glass side panel had a big scratch right out of the box. Cooler Master used to make reliable cases, but this one feels rushed and poorly designed. Save your money and buy something better — this one’s not worth the frustration. ... show more

    • READ THIS BEFORE YOU BUY
Style: Q300L V2 White
2/10 case. I have built my fair share of pcs. This case isn’t the worst I have seen, but it is very very far from the best. Everything about the case is great except for two things. One not so big deal is the expansion slots in the back are the punch out style so once you take them out there’s no putting them back in. Second by far the worst part is the the air flow is terrible due to the tiny holes all over. All they had to do was make the holes bigger and it would be an amazing case. I ended up chopping mine up to get better flow. Do better cooler master, this is an embarrassing product. ... show more
