A Closer Look - Inside

To access the interior, simply release the latch on the glass panel and remove the two thumb screws holding the solid side in place. The mesh cover above the glass is held in place nicely by amply strong magnets and may simply be pulled off once the glass is out of the way. In the interior, things look very simple. There are no rubber grommets, no well-placed, rubber-grommet-covered cable-routing holes or cable channels. In Win has included some holes, so you will be able to route everything, but the end result won't be as pretty as with most other cases out there. In fact, the bottom area of the body is the same as in the 309. What has changed is the top, where the mounting for the three 120 mm fans or AIO has been moved to be close to the mesh, which allows for a metal divider to thermally isolate it from the rest of the system. This mounting frame is also removable, which should make system assembly quite easy as well.


On the floor of the N515, you may install three 120 mm fans or even go for a 360 mm radiator, which will block any ATX board connectors on this bottom edge, so you will have to connect everything first before installing any cooling. However, I would suggest focusing on a good mATX board instead, which not only gives you some breathing room, but access to additional cable-routing holes. InWin does include a GPU mounting bracket as well, which seems a bit redundant as there are cutouts on the motherboard tray for the piece that ships as part of the accessories to be mounted there instead. This extra bracket mounts into the same place as any fans on the floor, so you would have to get rid of it with fans there anyway. Nonetheless, it is nice for InWin to give users this level of flexibility.


Behind the motherboard tray are openings for the CPU cooler mounting plate and several smaller ones for cable routing. That said, there are none at the very bottom edge of the chassis as there is no room, so any wires for ATX or E-ATX motherboards will have to run across the whole floor within the chassis. There are also two sturdy metal trays, which are held in place by a single thumb screw each. These allow for either a 2.5" or 3.5" drive to be installed.


A quick look at the inner ceiling of the N515 reveals a few cutouts for cables and tubing to pass from the top down to the chassis. None of these have grommets either, and the elongated one towards the left seems a bit odd. It was already present in the 309 and technically allows you to route cables to the top-left corner of your motherboard, but the sliver doesn't do much in keeping much of the cable hidden. Odds are you will see around 3–4 inches gently sloping down to that area of the motherboard. While there are three hooks for zip ties, this whole dividing plate feels a little under-utilized, and InWin could have added a few more such hooks for users to bunch PSU wiring away from fan or ARGB wiring that may be present up here.


In the front, the cutout for the two 120 mm fans can clearly be seen. And from this angle, there being no reason not to offer the possibility for 140 mm variants is apparent, as there is loads of room for it. On the motherboard tray, towards the front, are two more storage drive mounting plates for 2.5" variants. There is a central, well-placed cutout for leading the SATA power and data cables fairly efficiently to this area of the case, but it could have also benefited from a grommet.


The bottom third of the rear is taken up by the seven expansion slots. Interestingly enough, InWin has chosen to use classic instead of thumb screws to hold the covers in place. We mentioned this in the 2019 review of the 309 as well, and it seems nothing has changed. Judging by the placement of the bottom expansion slot, it becomes apparent that an ATX board is going to be a tight fit. Above that is the rear 120 mm Luna AL120 ARGB fan. In the very top is the PSU bay, which is accessible from behind the motherboard, so you won't really see it in the final build.


All the cables within the InWin N515 are sleeved black and of the default variety when it comes to the I/O and basic case elements. A small downside is that the HDD and power LED cables aren't marked with +/-, so you have to trial of error to get it right or look for the triangle marking on the plastic header. This is also something we mentioned in the 309 review.
