Antec ISK 310-150

If you´re looking for a Mini-ITX case for your new "high-efficiency" platform the Antec ISK 310-150 might be the right product for your needs. In 2009, some Mini-ITX motherboards were launched based on the Intel Atom platform. Antec quickly response was the ISK 300-65. At this moment, many other brands like Zotac, ECS, ASUS or even ASRock have taken the Mini-ITX market and expanded it to make the HTPCs powerful and affordable. There was still a limiting since many products offered low power PSUs (65 watts is simply not enough). If you want a Mini-ITX H55 paired with the Intel Core i3/Core i5 CPUs you need at least a 150 watts PSU to make sure you won´t have power-related problems. Benchmark Reviews tests the Antec ISK 310-150 which offers a new, elegant front finish with a 150 watts Flex-ATX PSU to power your system.

The ISK 310-150 is based on the first model: The Antec ISK 300-65. This product in particular was presented as one of the first Mini-ITX cases available for the ION platforms. The 310 number means they added a different front looks, and the 150, of course, means they changed the 65 watts PSU for a 150 watts Flex-ATX PSU. In our recent G.Skill ECO memory review, we added some power consumption results with a Mini-ITX motherboard and the ECS H55H-I motherboard. You might want to have a look at the results (see here) to understand that the Core i3 platform paired with a Flex-ATX PSU consumes no more than 100 watts at full load with the right components. By right components I mean a SLIM Optical drive and 2.5" HDDs with a low power PSU. If you use a high-end 700 watts PSU you won´t get the effectiveness you want for this kind of systems. So, basically, all the components I´ve mentioned here are needed to build a Mini-ITX PC with the Antec ISK 310-150 and they perfectly fit for this review.


Let´s have a look at the Antec ISK 310-150 Mini-ITX chassis to check the interior and exterior features. Finally, this could end being your next chassis for the HTPC you´ve been planning for months. Remember that if you´re looking for a HTPC with an ION-based system you might want to look the ISK 300-65 , since you won´t ever need more than 40-50 watts. Also, Antec launched the ISK 300-150, which is the same model as this one but with a black front finish similar to the ISK 300-65 for $5 USD less.

This product does not meet the applicable safety requirements for a fire enclosure when used in the vertical position. DIY users can use it as they see fit however be for warned. However if something does happen you can sue Antec as they provided a vertical mount.

Since when was your average PC case considered a "Fire Enclosure"????
And "applicable safety requirements" you must be joking.

What about the noise? Are the fans silent? What about vibrations?

It would also be interesting to know the PSU efficiency. And how a video card fits in there :).

Hi Zealot,
the fans are very quiet indeed, especially if you put them on the lowest rpm. PSU efficiency isn't great as it's a very basic PSU. It won't even give you 80% efficiency as it's not certified. If you wan't a good PSU for your ITX system look for other options then. FSP has some nice low wattage PSUs with 80 plus certified efficiency.

Does anybody know the max. CPU cooler height?

I think if you need a CPU cooler, it's too high.

This would be designed for Atom boards with integrated CPU and heatsink I think. It looks like the power supply has to sit over the CPU area.

Actually, I might be wrong, from the looks of this an LGA 1155 fits fine - pictured here with stock cooler. I'd imagine you'd be severely limited though - either the stock cooler or an AC Alpine 11 GT.

Have you tried reading the rest of the review, which has photos and descriptions of the interior?

FWIW, I just built a Haswell i7 system using this case.

I used the 65W TDP 4770S to reduce power consumption and cooling load. The rest of the system is fully-loaded: two HDDs, an ODD and even a GeForce 210-compatible display card.

The stock Intel CPU cooler fits just fine.

I replaced the Antec fan with a pair of PWM fans. It's worth noting that Antec changed the design of the plastic fan cover to be held in place with a couple of flat screws instead of the click tabs on the review unit. There was no need for me to disassemble the fan framework to swap fans. The 3-speed switch for the Antec fan simply clicks out of its rear-panel holder; no tools required. (If you wanted, you could add a second Antec fan with speed-control switch; the switch will click in to the reserved space on the rear-panel holder.)

Routing cables inside the case is tight, but not particularly difficult. I needed a couple of zip-ties to hold cables away from the CPU cooler.
