THE PHANTOM 630 INTERIOR
One thing you will notice is that neither one of the side panels has any kind of noise absorbing material on the interior.
The interior is really spacious which is natural since the Phantom 630 can accommodate up to XL sized mainboards.
All four 5.25" bays have quite sturdy locking mechanisms in place.
Right beneath we see three 3.5/2.5" drive cages with room for up to 6 drives.
A nice feature is the HDD pivot 140mm fan spot.
The drive trays are made out of flexible plastic so they are not very sturdy.
You can remove all three cages by removing 10 thumbscrews from the rear. The drives are also mounted from the rear.
For people who may choose to remove the drive cages NZXT has outfitted the Phantom 630 with two 2.5" SSD mounts placed beneath the mainboard tray.
You can use up to 10 fans with the built-in fan controller.
There's plenty of space (almost 3cm) for cable management between the mainboard tray and the right side panel.
Once you remove all three cages you will have access to the front area where you can mount a 240mm radiator vertically.
After that you have plenty of choices as to where you'd like to place the cages and how many of them you'd like to use (useful if you plan on mounting mGPU cards).
There are 4 large rubber grommet holes on the mainboard tray and a huge CPU cut out for swapping backplates with ease.
From the interior it's easy to see that you should be able to use a larger rear exhaust fan.
I was surprised to see that all 9 PCI slots are secured in place via regular screws. This is perhaps the sturdiest way but thumbscrews are easier to use.
Regardless of how long your PSU is the Phantom 630 Ultra Tower has more than enough room for it.
You can also mount a top 240mm radiator if the front and bottom spots are not sufficient for your needs.
