Days after NZXT announced a new line of all-in-one liquid coolers, the Kraken X40 and Kraken X60, they announced that they are going to be adopting the rapidly-becoming-standard 15mm fan spacing for radiators, and to that end they’ll be releasing an updated top plate for their Switch 810 case that is drilled for 15mm fan spacing for radiators. The original Switch 810 top plate is drilled for 20mm spacing. The industry has been split on whether 15mm or 20mm should be standard, but with 15mm looking like it, NZXT has thrown in with that crowd.

The new Phantom 820 is already compatible with 15mm radiator spacing. 15mm allows for shorter radiators and more efficient cooling. Yesterday they issued a press release to address concerns of current and future NZXT case owners:

We would also like to address some concerns this change may bring regarding our previously released products: Phantom 820 already features the required fan spacing specifications for the NZXT Kraken X60.

Switch 810 has already begun production with revised top steel panels which allows for both 15mm and 20mm spacing.

Phantom 410 and Tempest 410 will happily accept the Kraken X40; however they will not be able to natively support the Kraken X60 due to their inherent hole spacing. At the moment, NZXT’s Switch 810 will be the only case receiving revised top steel panels for native Kraken X60 support. If you already own a Switch 810 and wish to purchase an NZXT Kraken X60, you may contact NZXT Support for a free replacement. The revised steel panels utilize screws for its installation, allowing users to easily replace the top steel panel with a standard Phillips head screwdriver.

The Kraken X40 and X60 will be available soon, and should come in at $99.99 for the X40 and $139.99 for the X60. The compatibility list can be clicked for a large version.
