In Win 303 ATX Mid-Tower Case Review

Cases & PSU/Cases by leeghoofd @ 2016-11-04

For those that are not familiar with any of the In Win products, let us describe the Taiwan-based In Win company as a luxurious enclosure manufacturer, using high quality components, especially in their exclusive designs. If you want a case that stands out from the crowd their gamma will for sure have a model that will perfectly suit your needs. The In Win 805 we reviewed was a premium case with tempered glass all around; In Win even has more classy looking models in their lineup than the 909 full-tower model we also tested. Each year at Computex they have an absolute stunning case or prototype on display and they are accumulating the awards year after year. Normally an exclusive design goes hand in hand with a beefy price tag, however with the 303 In Win launches a high grade mid-tower enclosure that is sort of affordable. Time to open the box and see what this In Win 303 has got in store for us.

The Build

The Madshrimps compatibility hardware comprises of the following parts:

MSI Z170 XPOWER Titanium Gaming Edition
Intel i7-6700K
Be Quiet Silent Loop 240
16GB G.Skill 3600C16 RAMs
1 x MSI GTX 1060 graphics card
1 x Western Digital 2TB Caviar Green Hard Drives
1 x HyperX 120GB SSD
Seasonic Snow Silent 750W Power Supply.

The build was pretty straightforward! A good tip is to install the PSU first in its dedicated chamber and properly route the power cables. Afterwards position the motherboard and install the cooling setup last. The Be Quiet 240 radiator was mounted initially on the top support, later we installed it also on the bottom of the case. The cable routing and co was relatively easy as there are enough well positioned cut-outs and plenty of clearance (32mm) between the motherboard tray and the side panel.

As you can see we installed the PSU in a configuration so it removes hot air from the case's innards, however imagine if you opt to install a 360 radiator: it will dump the generated heat straight into the PSU or on the backside of the PSU. I would have loved to squeeze the Be Quiet 240 radiator inside the top chamber, though this would require a huge cutout to be able to route the hoses and pump unit of our AIO setup.

If one uses a DIY water cooling, the current design is no problem, of course also not with an AIO that has removable tubing, Thinking not many will go this far and keep their AIO unit as it came out of the box.

Plenty of correctly placed cut-outs facilitate the cable management. Like mentioned before, too bad we could not install the bigger 3.5" HDDs at the motherboard side. These remain sandwiched between the motherboard panel and the side panel. Via the AIDA64 software we measured a temp increase of around 8°C versus positioning the platter on the bottom of the case on just a foam pad (not secured).

The In Win 303 supports power supplies up to 200mm in length to allow the power cables to be routed through the bottom hole. The Seasonic Snow Silent we are using here is perfect for the task as it measures just 170mm in length. Thus leaves plenty of room in the dedicated side chamber to tuck most of the cables away. Though keep in mind that with our cooling setup the hot air has to pass from the radiator towards the side panel, so better keep it tidy for optimized airflow.

Another option instead of a top mount when utilizing an AIO is to mount the radiator on the bottom. All depends on what you prefer and how much or good you want the airflow inside the case to be.

One small point of criticism is that the tempered glass side panel leaves a tiny gap, so dust seems to be a bit more welcome than expected.
