The Case – Features and Specifications –

From In WIn’s webpage-

Modeled after one of the most recognizable jets in the world, the features of the all-new In Win B2 Bomber will surely get you noticed amongst a crowd of gaming elites. If the auto-sensing front door doesn’t do it for you, perhaps the W-shaped side intakes inspired by the Stealth Bomber will. Throughout the chassis you’ll find four high quality ceramic fans, lasting longer and running quietly to provide a superb cooling process. Ultimately stylish and completely innovative, this chassis will have you “flying” over the competition.

Before we open the box we would like to share a little about how we took notice of In Win as a company.  We attended CES 2009 in Las Vegas and one of our "teams" roamed the floors looking for intriguing hardware that caught our eye from companies that we either deemed "on the rise" or "lesser known."  We came across In Win’s display with their newest line of power supplies that caught our eye.  After talking to one of the enthusiastic representatives about the PSUs, she took us over to show us their new case selection.  We had previously not given much thought to In Win cases or PSUs so this was a great opportunity to be "sold" on what they were showing us, going into it with no preconceived notions.  Upon seeing the variety of cases, the representative asked if we would be interested in reviewing one or more of them and naturally we agreed to do so.  We also have an impressive looking In WIn Commander 1200 Watt PSU up for review that is currently in line for testing on the Sunmoon unit that Mike (owner of Xtreme CPU) is mastering before any numbers are published.  Let us take a look at what is inside…

Nothing exciting here, just a standard retail PC case box bearing a picture of the case itself, the features, specifications, and a cockpit picture revealing the aviation theme of the case (if the name itself was not already clue enough.)

Some closeups of the features In WIn promises to bring us. 


Standard but effective styrofoam packaging.  This case is relatively heavy for its size and comes out of the box feeling very sturdy. 

[timg]dsc_0076.jpg[/timg]  [timg]dsc_0099.jpg[/timg]  [timg]dsc_0105.jpg[/timg]  [timg]dsc_0107.jpg[/timg]

Shots of all sides of the case straight out of the box.  You can see the continuation of the aviation theme with the markings and side vent.  The front panel of the case has a powered drive bay door that will be displayed more thouroughly later on.  One of the first unique features is that the case uses a military thumb-switch inspired locking mechanism rather than your standard thumb screws. 

The locking mechanism for the side panels worked very well and is a viable replacement for the more traditional thumb screws.  We see holes in the rear panel with rubber grommets for water cooling tubing as well as the 120mm exhaust fan and a top mounted PSU.


Removing the rear side panel reveals a pretty standard non-removable motherboard tray.  One feature that is not present is any active attempt to give the end user a variety of wire routing tools such as pre-cut holes or tie downs.


Underneath we find high quality rubber feet that are screwed to the base of the case, something that you don’t appreciate until you lose a glued on foot and have to prop your case up with a John Steinbeck novel.  The front intake is right at the bottom of the case, which doesn’t bode well for a system where the case is placed on carpet, though as we will see later the primary intake fan is filtered.

[timg]dsc_0135.jpg[/timg]  [timg]dsc_0145.jpg[/timg]  [timg]dsc_0151.jpg[/timg]

Once the side panel is removed we can see that the V shaped "wing" on the side is in fact an intake vent (also filtered) and the case comes with a stock cooling duct, which most end users will promptly remove.

In Win includes a drop down dual 80mm fan shroud that can be configured in a variety of directions.  The fans can be reversed or lifted up to provide whatever cooling setup is optimal for your system.  One nice thing about the shroud is that it can be easily removed for a user that does not want to use it for a variety of reasons.


Here we see the fatal flaw that the B2 brings to the table.  If using the 80mm fan in the upright position you are limited to less than 9" of graphics card length, or ~10 1/2" when in the standard position.  This eliminates the possibility of using many of the high end graphics cards available.  GTX 260/280 *may* fit with a PCB length of 10 1/2" inches, though there would be virtually no room left if in fact the card was able to fit.  We do not have one on hand to verify one way or the other.  HD 4850’s with a PCB length of 9 1/4" do fit, although the use of a horizontal 6 pin PCI-e connector effectively increases the length of the card enough to make things very tight.  This is certainly a problem that In Win needs to address if they hope to be competitive in the enthusiast chassis market in the near future.

You can see that when using a longer card such as 4850/4870/3870X2/8800GTS/8800GT/8800GTX (won’t fit period)/9800GTX or GTX200 series, chances are you will have to remove the card if you want to access the front intake fan to clean the filter.  We would like to see a very easy filter removal system when using a fan filter in a case to encourage the user to actually clean the filter fairly often to keep airflow efficiency at a maximum.

Here we see that all the fans come with rubber corner grommets that reduce vibration very effectively.  The fans are rebadged Yate Loon fans and are honestly some of the best "stock" case fans we have seen. 

In Win incorporates some very easy to use and toolless drive mounting rails that double as vibration dampening at which they are very effective.

As you can see, there are enough rails to fill every drive slot in the case and a convenient caddy can store the extras in a spare 5 1/5" bay and be accessed from within the case or from the front after removing the front panel.  These are very easy to use, you simply insert the metal nub into the screw hole on your drive and slide the drive into the bay and it clicks into place.  Smooth and toolless, without the ugly multi-colored clips and latches incorporated in some other "toolless" designs.

Continuing with the aviation theme, even the manual override switch to open the power operated door hatch when no power is available is marked like a military plane.  It is nice to have a manual option for when the system is powered off or unbuilt, or if the novelty of a mechanized front panel wears off at some point.  We prefer you make some sort of Transformers noise or the "hissing" noise of the hatch door on a cryogenic freezer when operating the door to prevent the novelty from wearing off.


Just to the left of the motorized door’s touch sensitive action switch is a small panel featuring 2 eSata ports, 2 USB 2.0 ports, a Firewire port and front panel audio.  We were playing with the auto light sensing settings on a new camera and thought this shot turned out very cool.


Here is the door on its way open or closed, the hinges are relatively sturdy but are really only designed to go up or down, side to side force would not bode well for the longevity of the motorized mechanism.  Nor would it bode well for your chance to have a legitimate reason to make Transformers noises by yourself.


A fancy GIF of the door in action.


Whether you like the appearance of this case or not, it is hard to deny that In Win is a company coming forward with some unique features and we sure hope is one "on the rise" to becoming a major competitor in the consumer enthusiast market.  We hope they expand their chassis line into broader range of styling cues to appeal to a wider base of end users and give us more options to choose from.  Overall we liked this case and it has some very promising features, but we do not feel it has reached its "maturity" in terms of overall PC case value.  It is currently priced at $110 on Newegg but it may be hard to justify spending $100+ on a case that may or may not be able to hold the components you choose now or in the future for your system without some struggle or modifications.  Much could be done with only 1" more in case length to ease the difficulty of installing or removing components.

– Sturdy and well built
– Customizable cooling options
– Excellent stock fans
– Excellent drive retention
– Everything has rubberized vibration dampening
– Styling?
– Mechanical door?

– Tight fit for many cards
– Slow fan filter removal
– Styling?
– Mechanical door?

Thank you to In Win for providing the case and we hope constructive feedback will be taken into account for future chassis releases.  Discuss this review here in our forums.
