$4000 Build

First Impressions

As usual another solid & heavy built Case from Inwin. I was pleasantly surprised how nicely the window opens (with a single push button handle). It makes perfect sense if your overclocking and need to get in and out of your Rig fast, this is extremely practical, most tempered glass Cases, such as the Corsair 570x, have large bolt-like screws.

Radiator options

I tried to install a 280mm Radiator & I can confirm, it does not fit anywhere in this Case unless you want to dangle it off a few cable ties. This case will however fit 120mm, 240mm, and 360mm Radiators. For testing purposes I tried to install my 240mm Radiator on the floor, it didn't fit because the Motherboard was in the way however if you have a Micro ATX Motherboard it will definitely fit, there are screw holes there for fans you could use for a Radiator, even though you're not really meant to (it ends up blowing hot air back into the case).

Mounting Radiator Backwards

If you have an open loop Water Cooler configuration (Pump can be removed from Radiator), you could easily install the Radiator at the rear however with AIO Coolers this is not possible, I really wish Inwin made a bigger hole above the Motherboard so you could fit the pump through from the back. If you notice, on closed loop AIO systems like mine, the pipes poke out so when you close the Window it kinda squishes them down. That's why the floor setup was appealing to me in the first place, as it made the pipes flow nicely.

Cooling Performance

Sufficient... ish, depending on your hardware selection. The Inwin 303 comes with zero intake fans & a single extractor. I added 5 extractor fans which was a must. It does the job, luckily Inwin made a vent on the rear panel to help the hot air escape from the Radiator. In my experience, I've found that Inwin tend to make Cases that look awesome, and are not necessarily optimised well for cooling. The sales manager from Inwin made a good point though when I was talking to her about it last week at Armageddon. "If you use water cooling on all the components, it's not an issue". Which is true, this is what the Case was designed for.


I see the point with adding the NVIDIA logo on this Case, since it's a NVIDIA build, however I wish this was an optional / removable sticker. I have had many customers comment that they like the green but dislike the advertising.


It's one of the few Cases which actually get me excited about gaming just by looking at it. The toxic green entices me to play Doom. This Case has it's ups & downs, but overall I love it & am seriously considering it for my next personal build.
