Craig’s Ryzen Manta ITX Build (PT 1)

With AMD’s Ryzen launch, I’ve started gathering parts for my new PC. I’m really looking forward to this build, as I’m anxiously awaiting mITX boards for AM4 processors. With that in mind, I purchased a NZXT Manta mITX case. There are a few reasons for choosing this particular case, not the least is that NZXT has a history of building quality enclosures that aren’t just a square box. I tend to like cases that standout instead of trying to blend in. Another is the support for dual 280 radiators, and a reservoir, as this will be my first custom loop build. No, it’s not the smallest ITX case out there, and I’m fine with that. To me it’s the right size for a complete gaming rig, that even with all the bells and whistles, still has a smaller footprint. Let’s take a look.

NZXT calls the Manta a “High-performance small form factor mini-ITX case.”

“Bending the rules, softening the lines, putting everything out there for everyone to see. We took ITX to a whole new level with a revolutionary design and uncompromising quality. The result? A clean, easy build and blazing performance. Go ahead, show it off.”

The large side panel window gives an unfettered view of the interior. More on that in a bit, but first let’s take a trip around the outside.

As you can see, all the outer panels are curved, and I like the contrast of the matte white paint with black accents. The side panels stand out from the sides a bit giving the chassis room to take air in, and exhaust it.

Around the back there is additional venting in the top panel, the opening for the motherboard I/O ports, 2 expansion slots, and the opening for an ATX PSU. The side panels are held on with captive thumb screws.

Up top there is the power button, 2 USB 3.0 ports, and the headphone and mic jacks along with the power LED.

With the side removed, we can get a better look at the inside. The Manta comes with 3 120mm fans preinstalled – 2 in the front, and 1 in the rear. There is also 2 2.5” drive mounts on the right side. There are plenty of cutouts in the motherboard tray to make for a clean build, and the motherboard standoffs are preinstalled.

Next to the 2.5” mounts is an area that will allow for the routing of cables while keeping them hidden. It is also fairly deep to help keep the 24pin snake under control.

The PSU shroud covers most of the bottom, and includes an opening for your GPU cables, stopping short of the front to allow for the installation of a radiator.

Up top there is the mounting point for a second 280 rad, or 2 140mm fans.

With the right-side panel removed, we get a look at what the Manta has available for cable management. There are numerous cable tie down points, and the curve of the panel further increases the space available. As you can see the bottom portion is wide open which will make cable routing a snap.

A closer look at the bottom shows the removable filter for the PSU, and the mounting point for a 3.5” storage drive.

Also on the back there is a fan hub with support for up to 8 fans.

With the front cover removed, we can see the front filter, which is easily removable.

Here we see the 2 preinstalled 120mm fans, and the mounting points for 140mm fans and/or radiators. The top and front covers come off with a gentle tug, and are easy to replace.

On the bottom, there are 2 large U-shaped feet that provide a good deal of clearance allowing the PSU to breathe freely, and 4 rubber strips to keep the case in place on your desk.

Well there’s a look at my new PC’s home. I hope you enjoyed it, and stick around, as I will be looking at the other components that will make up the build, and of course the build itself. For now, the Manta will get boxed back up, and shipped off to my good friend and fellow RTP member Ian aka @torn_tv. He will be repainting the interior all white, and applying some vinyl decals for me.
