Final Thoughts
Wow, what a great little case! I really like the construction and the style of MasterBox Q300L. Right from the start, I could visualize the possibilities of this case when it comes to cutting and painting it. CoolerMaster really gives users to choose their style with this case. Users have a choice of using magnetic dust filters, positioning the case on the side or adjusting the IO panel into the position that is most beneficial. The clear window stretches a full length of the case giving an option of showing off your modding skills. The only downside of this case is that the side window is made from plastic and not tempered glass. There is some radiator support in MasterBox Q300L as well. I found a couple of spots where you can install a 120 mm or even 240 mm radiators for either All In One or custom loop solutions.
So how much is this case you are going to ask? Currently, CoolerMaster MasterBox Q300L retails for $ 39.99 USD which puts this case in the budget category. But let’s face it, there is nothing on the budget about this case. Q300L is stylish, light and full of customization to make this case “Yours” For the price you can’t really beat this. If you looking for similar cases in the same price range, check out Cooler Master MasterBox Lite 3.1 as it is very similar to Q300L and Fractal Design Focus G.
Can you install a 240mm radiator to the top? Specification does not say but the top panel seems to be the same as the front…
Can you clearify one issue for me ? Because the specification table on the first page says CPU cooler clerance is 157 mm, but on the 3rd page you said it can support about 160mm CPU Cooler Height, which makes me confused which one is right. Plus one thing i see the cooler you used on the installation is may be Cooler Master Hyper 212, right ? I love this case so much from the fist sight and i dont want to replace my Thermalright Legrand Macho either. So you guys can help this issue ? Cheer and love your review.
I’m with Tuan. Does it really fit 160mm coolers?
Tamas,
Is it possible to fit a 240 up top, yes it is. However keep this in mind there are no mounting for it. There are no mounting holes however, If you REALLY want to put a 240 up there you can. It would be a pain because you will have issues with the motherboard being in the way. IF you go that route, go with a slim 240mm radiator. If I remember correctly, most manufactures make them in 37mm height.
Hope this helps.
Tuan,
So here is the deal. I measured the distance from the motherboard tray all the way up to the window. So this is why you see 160 in my notes. However if you want from the motherboard tray to the window, e mail and i will re-measure it for you.(alex@modders-inc.com)
The cooler I am using is in fact Hyper 212. If I am not mistaken the whole cooler is about 158mm. But I would not use it in this case. Get a AIO 120mm solution. It will look much cleaner.
Cheers,
Him I built a my first pc with this and right now I’m trying to install fans the, Corsair LL120 RGB but when I try and use the screws that came with the fans they are to big and the screws that came with the case are to small. If anyone knows a way around this I’ll be looking, plz reply ty
Would it be possible to insert a full ATX MoBo by flangin it behind the PSU? I really like this case, but I just bought an ATX motherboard.
Yes it could but with some compromise:

I just fit a cooler master 212 turbo cpu cooler in my cooler master case with a few mm to spare and so I u can fit up too a 163mm cpu cooler in ur welcome:)
I have tried 140mm on the top of the case and it does contact the motherboard when installing them up there so i recommend installing the fans first and pushing the motherboard down towards the psu area to stop it from contacting the fans.
What is better: Q300L or Lite 3.1?
I unscrewed the HDD panel and it came out and I was able to screw it back but it won’t let me take take the HDD panel off again. How could I take it out?
