InWin 303 Mid-Tower Chassis Review

Complete System

Installing our components into the 303 couldn’t have been easier, as there is a laughable amount of space on the chassis interior that even our massive Sapphire R9 280X Tri-X Toxic graphics cards look relatively small. Without a doubt, even the biggest graphics cards on the market will have more than enough room in here.

While there are no front panel mounts for cooling, there’s a huge amount of passive airflow from the bottom of the chassis, and more than enough room to fit a bank of 120m fans below your GPUs for added cooling performance. Of course, if you’re only rocking a single GPU configuration, as most people are doing these days, you’ll also find room for radiators in the base of the chassis too. With so much room in the front section, a large reservoir and pump configuration isn’t likely to cause an issue either.

There’s good clearance for wider expansion cards too, as well as many of the high-end air coolers on the market, which is good news for those wanting something like the Noctua NH-D15 or the be quiet! Dark Rock Pro 3. The 120mm fan in the back is easily removed too, so if you wanted a simple AIO cooler here, that shouldn’t be a problem either.

Here you can the PSU tucked behind that honeycomb effect fan/radiator mount. It does mean you can see the cable connectors, but a few cables ties and a bit of braiding go a long way to keeping this presentable.

Speaking of which, it seems InWin still don’t know how to layout cable routing holes, which is a shame as they didn’t get it right on past chassis and it does mean the motherboard 4+4 pin has to travel along the top of the board and the 24-pin has to travel down quite a bit to the board. For this reason, I deployed braided cable extensions to keep the build looking clean and I suspect many others will want to do something similar.

The same goes for the GPU cables, there’s no idea routing solution here, so I passed the cables under the cards, which would obviously cause some issue with fans in the base of the chassis. Of course, this all depends on your GPU configuration, where the power connector is placed and so on, but as you can see, it still looks neat and tidy when you take a little time set it up.

All panels back in place, we can still see a nice view of our components through the tint in the glass. It’s a bright sunny day here, so reflections are really causing hell with the images, but you can honestly see through more than the pictures imply.

Getting in a little closer, you can see a little more clearly. It’s going to be important to your build to get that cable routing neat and tidy, it will be visible.

Hitting the power button, and you can certainly see the interior a lot more clearly. LED lighting on the motherboard and graphics cards shines through very clearly and that’s going to be awesome for those with interior lighting aspirations.

The InWin logo, the USB ports, and audio jacks all glow beautifully, with a white LED light behind their blue covers that looks really cool, just giving the whole chassis a little bit of extra flair overall.
