In Win 703 Mid Tower Chassis Review


Now with the exterior formalities out of the way, we can get into the meat and potatoes of the 703 and find out what it has to offer you. Starting from the rear you’ll see two thumbscrews per side which hold the two side panels on. Remove the screws and panels and we’ll work back from the front panel again.

If you peak along the left side of the front panel when it’s facing you, you’ll see three red tabs holding the front panel to the chassis. These are easily popped off but be gentle as if you snap these your panel won’t reconnect properly.

Once you pop the tabs and open the front panel you’ll notice the cables running from the top, which consist of one black cased cable that is your USB 3.0 connector, a Molex USB connector that carries both 2.0 USB ports and another Molex connector carrying the audio. Along with those there are HDD LED, PLED and PWR Switch Molex connectors. Next you’ll notice the open 5.25” drive, along with two more below it with breakaway covers, once again these aren’t replaceable so one they are off they are off for good. Below there is space for two additional 120 mm intake fans to the rear of the two fan filters.

Turning to the cable stowage side of the chassis you’ll notice the 115x135mm gap at the top right. This space allows you to interchange cooling units without removing the motherboard.

We think this space definitely could have been bigger given adding an extra 10-20 mm in either direction would ensure the fit of many more cooling units and wouldn’t’ have affected the set up or integrity of the chassis, but it fit for our set up. Below that you’ll next notice an 80 x 285mm cut out which allows for more cable management and accessibility to tighter areas of the lower chassis.

Turning to the other side is where you’ll notice the interior space for parts and the four drive slots which are compatible to install 2.5” or 3.5” drives and an additional 2.5” tray sits atop these slots.

inside_Fotor_clipped_rev_1If you take a close look, it is apparent that In Win intended for the availability to have at least two more 3.5” trays as the guide rails on the right edge along with the two locking notches would suggest.


This is potentially an add-on if you need more than the four already available slots, but would require some assembly. One thing we thought of that In Win may want to consider in the future is making the 3.5” slot trays a removable structure. Given we used an Icy Dock with four slots for storage it would be nice to be able to remove the internal drive tower to allow the air flow from the bottom fan more directly to the central components of the tower. Next you’ll see the three 5.25” drive bays above to which one has a plastic locking mechanism which works quite well with our four-bay Icy Dock. If you chose to use the remaining two 5.25 drives you’ll have to secure your drives with the provided screws or other locking mechanisms. The 703 features high expandability which boasts housing high-end graphics cards up to 408mm (16.1”) and CPU coolers up to 160mm (6.3”). Space is not an issue for the majority of builds you will use such a chassis for.

InWin Bottom 2

Along the bottom if your PSU doesn’t exceed 170mm you’ll notice the availability for yet a fourth 120mm fan along the bottom of the chassis, with this much air flow available it’s clear In Win has a dedication to keeping your components cool.
