The MasterBoxQ300L is your straightforward option in the lineup of the brand new MasterBox Q-series from Cooler Master. A series that might be small in size but excels in functionality and modularity without compromising on the thermal performance.Although the size wouldn’t tell, the MasterBox Q300L supports a standard ATX PSU which we don’t see often in the market with this size.

Cute and my dog loves it
My dog loves toys she can play rough with both her teeth and paws and this one was loved the second it came out of the packaging. We liked that the eyes are sewn patches so nothing to swallow if it detaches (other than the material). The knotted ropes that form it’s arms and legs actually move through the body from side to side, which makes tugging games fun and interesting. We also liked that there were no dangling easy-to-chew off bits, for example, the ears are tiny nubs so she can’t get them off with her teeth easily. The stuffing is also firm and full so it’s like a soft toy to cuddle up with but with rope limbs to sink her teeth into. She rates it highly.

Chew proof except for stuffing
Color: Grey, Color: Grey
I left Sage with her new chew toy and was distracted by something in the other room. I came back not 5 minutes later, and this was what I saw! Stuffing all over the floor! And that was just the beginning. By the end of the day, I had cleaned up stuffing several times from separate sessions with the toy! The rest of the poor toy is holding together, except that it has lost a couple of squeakers. I don't know whether to recommend it or not. Sage is exceptionally, extraordinarily, extremely, immensely, and profoundly aggressive when she chews (on inanimate objects only -- no humans or other animals!).

Great hit with my dog
Color: Grey, Color: Grey
The gray rhino is a great hit with my dog. She's a medium size golden (53lbs) likes to chew and tug, but she is not not too aggressive with toys, and this has become her favorite toy. Over the last 2 weeks she's removed the top arms from the body and "killed" one of the squeakers, and the arms are now a separate tug toy. We could have put the arms back, but she figured out those come off, and she would take them out again. The armless rhino is still the one she carries around from room to room, plating tug and fetch with every day. The toy is very well stitched, the fabric is of good quality and there are no small pieces that come apart to be swallowed. It gets dirty from all the playing so I plan to throw it in the wash every month or so.

Great toy
Color: Grey
My girl loves this toy. She has a lot of toys but this is her favorite. She is a 26 lb mini golden and we have had it over a year. It is just now starting to show wear. Once it is completely worn out I will buy it again!
