The front facade has been constructed from plastic and aluminum and features a colored border – red on our sample. Red highlights are also found around the external 5.25" drive bay as well as at the top and bottom of the front panel. The panel itself is covered in a thin brushed aluminum sheet which has been given a black finish. It looks rather sleek. The only other detail is the chrome “In Win” label at the top.
On the very top of the front panel embedded in that red band is the I/O panel which features two USB 2.0 ports and just a single USB 3.0 port along with two audio jacks for headphones and a microphone. Users will also find the storage activity light along with the power button. The 703 measures 432mm tall, 210mm wide and 477mm deep giving it a capacity of 43L, making it slightly bigger than the Corsair Carbide 100R. Both versions of the 703 come with a case window that has been custom built for this enclosure. The window looks quite unusual as it protrudes from the case door by 11mm. This is a neat effect and makes the 703 more eye catching than it would be otherwise.
The opposite case door also features a 7mm raised section which we suspect will come in handy when it comes to cable management. Both door panels are secured via a pair of thumb screws. Around back we find two 1" water cooling holes followed by a 120mm exhaust fan and a cutout for the motherboard’s I/O panel. Below that are seven expansion slots and like the Corsair 100R they are accessed externally. Finally at the bottom we have a slot for an ATX power supply.
Underneath the 703 are four large plastic feet that raise the case 17mm off the ground. There are also two separate dust filters, one for the ATX power supply and one for an optional fan location. Inside the 703 we find what looks to be an almost identical layout to the Corsair 100R. The motherboard tray features a similar sized 133 x 114mm cut-out as well as a number of similar holes for cable management.
Mounted in the front section of the case is the hard drive cage which uses similar tool-less drive caddies to what we found in the 100R (and yes, there are four of them). However, In Win has made better use of the space by adding mounts for a 2.5" SSD on top of the drive cage. This means the 703 can handle two 5.25" devices, four 3.5" or 2.5" drives plus the extra 2.5" drive. The external 5.25" drive bay comes with a tool-less attachment that oddly features a lime green twist knob. This looks out of place in the 703 and is clearly a recycled part from another case. In Win also dropped the ball on the I/O cables which aren’t colored black like they are in the Corsair 100R.
In Win says that the 703 supports a maximum graphics card length of 408mm and that is true, at least for the primary PCIe graphics card. Any additional graphics cards will be limited to 290mm due to the non-removable hard drive cage, though that’s enough for high-end cards including the GeForce GTX 980.
There is loads of room for the power supply as well – up to 220mm or 170mm with a bottom fan installed. While we had an issue with the Corsair 100R’s limited CPU cooler height, this doesn’t appear to be an issue with the 703 as it can handle tower coolers as tall as 170mm.
The 703 allows for two 120mm front fans (fan filters come pre-installed). The rear 120mm LED fan comes with the case while there is room for an additional 120mm fan in the bottom of the case. Surprisingly the 703 doesn’t allow for top-mounted fans. Unfortunately, the included 120mm LED fan doesn’t feature a 3-pin power connector so it cannot be connected to the motherboard. Instead In Win has gone with a 4-pin Molex power connector which is a lot less convenient in our opinion as the motherboard cannot control the fan speed. Still, other than the fan connector, oddly colored 5.25" tool-less module and non-themed I/O cables, the In Win 703 is well designed inside and should make building a PC in a breeze.
In Win 703 Installation
The installation process for the In Win 703 was similar to that of the Corsair 100R, though with greater support for tower style CPU coolers we had an easier time finding compatible hardware. With the doors removed, the In Win 703 is just 5mm wider than the 100R and yet it can handle CPU coolers that are 20mm taller. As mentioned, this is due to the design of the case window which juts out by 11mm.
In Win has been able to recess the motherboard tray a few millimeters back as well which helps create more headroom for the CPU cooler. This luxury was afforded by including an 8mm bulge in the right door panel. With the Intel X79 motherboard installed we were able to install a massive tower style CPU cooler such as the 159mm tall Prolimatech Megahalems Black and still have over 10mm of room to spare. This feature alone makes the 703 a better enthusiast case than the 100R. Another problem we had with the Corsair 100R was getting the right door panel back on once the 3.5" drives were installed. This is because the power cables simply stuck out too far and would come in contact with the door causing us to manhandle it back on. This isn’t a problem with the 703 as it provides plenty of room for cables behind the drive bays and the motherboard tray.
Fitting everything into the In Win 703 was a breeze and despite installing high-end hardware we found it all fit without any fuss. Gamers would have no trouble getting one, two or even three GTX 980 cards into this case. That said, if you plan to kit this case out to that extent, you’ll have to address its cooling as a single 120mm exhaust fan won’t suffice. Similar quality LED fans start at around $7 and we recommend picking up two of them to be front mounted. When it came to cable management the 703 has less cut-outs in the motherboard tray than the 100R, but with more room for hiding cables behind the motherboard tray it makes for a very clean and tidy build. For a compact mid-tower the In Win 703 is damn near perfect with the exception of just a few small details. The green 5.25" tool-less adapter is a mystery though thankfully you can’t see it through the window easily and it can simply be removed if it bothers you. The front panel cables look like something we’d expect to find in a generic $20 case and they stand out enough to spoil the build for us, even if it’s a minor issue. Overall, In Win got all the major stuff bang on and the few faults we found are relatively nitpicky.
