SG16Serious Gaming Power in a Tiny Box!

Are you a gamer who wants extreme gaming capability in a tiny package? Then the $1,500 High-End Mini-ITX Gaming PC Build is for you! This system takes up barely 1/3 the space of a typical gaming tower while packing in the same performance, making it perfect for gaming on the go or in your living room. In other words, despite its compact size, the $1,500 Mini-ITX Gaming PC Build is a totally legit high-end gaming PC, the equal of massive PCs that cost the same or more!

This Month’s Build, Powered by AMD and Nvidia!

For October 2023, this build gets a serious upgrade in gaming power, moving to the ultra-fast Ryzen 5 7600X six-core, 12-thread CPU, which is supporting the Nvidia GeForce RTX 4070 12GB video card, by far the most powerful video card ever released that can fit in an ultra-compact system like this one. This combo is made possible by the release of the new lower-cost A620 chipset from AMD (perfect for an ITX system) and a price cut on the 4070. Just a few months ago, you could never get this much power into our $1500 budget for this build!

Also on the build list is 32GB of speedy DDR5-6000 RAM, along with a quick 1TB PCIe Gen 4 solid-state drive. The build comes together in the compact SilverStone SG16 chassis and uses a 120mm liquid cooler to maximize the system’s cooling performance. Finally, feeding this system is a quiet, efficient 500W power supply. Learn more about building in the SG16 case in our full review below.

The DIY Build

  • AMD Ryzen 7600X

    CPU –

    AMD Ryzen 5 7600X

    $249
    AMD has done it again with Zen 4, simply smashing through the performance barrier in all respects. The 6-core, 12-thread Ryzen 5 7600X is up to 15% faster in games and 25% faster in content creation than its predecessor, while offering the latest connectivity standards thanks to the AM5 platform.

    The Guru’s Tip

    This CPU does not include a cooler, so make sure to pick up the model we list later in this guide.
  • Gigabyte A620i
    Click to Buy
    Motherboard –

    Gigabyte A620I AX

    $140
    This affordable AM5 board allows you to jump into AMD’s latest CPU ecosystem at a great price. It offers built in 802.11ax (WiFi 6), a Gen 4 M.2 slot, a Gen 4 video card slot, plus six USB ports (including a Type-C). The key difference between the A620 chipset on which this board is based and the B650 chipset on boards costing twice as much is slots and ports, but for an ITX board, that has little impact. There’s only so much space for these things in a compact form factor anyway, so for mini-ITX, A620 is a perfect match!

    The Guru’s Tip

    The A620 chipset doesn't support manual overclocking, so we go with the pre-overclocked 7600X CPU above!

    Video Card –

    Zotac GeForce RTX 4070 Twin Edge12GB Spider-Verse

    $550
    The RTX 4070 offers amazing performance and amazing efficiency, making it the perfect GPU for any high-end gaming rig! This model’s dual-slot, dual-fan cooler will keep temperatures in check and noise levels down, without filling up your system. Plus it has plenty of room for manual overclocking. Even better is the price, which is actually below Nvidia’s MSRP, a concept that had almost vanished in the last generation! Note that this model has a Spider-Man theme, but it’s all optional, in the form of stickers and an add-on magnetic backplate, so you can choose to go with the standard styling if you wish.

    The Guru’s Tip

    While most RTX 4070 models will not fit in the case we recommend, this one, at just 9.7" long, will have room to spare!

    G.Skill 2x16GB Flare X5 DDR5-6000 CL36 EXPO

    $93
    To get the most out of AMD’s latest CPUs, you want fast RAM, and DDR5-6000 is the sweetspot not only in terms of price, but in terms of the AM5 platform. It allows for the optimum settings and highest overall performance. This Flare X5 kit from G.Skill is specially designed for AM5, thanks to the enhanced 36-36-36-96 EXPO timings that can be loaded easily by the motherboard.

    The Guru’s Tip

    This DDR5 kit is a perfect match for the motherboard we recommend.

    Solid-State Drive –

    WD_BLACK SN770 1TB NVMe

    $60
    WD knocked it out of the park with its ultra-high-performance, bargain-priced SN770 PCIe Gen 4 drive. Optimized for excellent real-world performance thanks to WD’s years of SSD development, it easily keeps up with much more expensive drives. This 1TB model can provide sequential read speeds of 5150MB/s and write speeds of 4900MB/s.

    The Guru’s Tip

    Remember to install this drive before you install the motherboard in the case!
  • SilverStone SG16
    Click to Buy
    Case –

    SilverStone SG16

    $86
    Coming in at just 13 liters despite impressive component compatibility and exceptional airflow, the SG16 stands alone. There are smaller “kick-started” cases out there, but they often come with a whole lot of “gotchas”, one of which is always an exorbitant price! The SG16, on the other hand, is a value-packed option designed by the biggest name in the ITX industry, SilverStone. It has 120mm fan mounts front and rear (almost unheard of in this size-class), and it can fit video cards up to 10.8″ long.

    The Guru’s Tip

    This case is also available in a sleek white finish, which is listed on the same product page.
  • Scythe Kaze Flex II

    Case Fan –

    Scythe Kaze Flex II 120mm Fan

    $16
    Scythe has been in the cooling business for decades, and we actually have some of their fans from the early 2000s still running in our systems! What makes the Kaze Flex II and its predecessors so good are the high-quality fluid dynamic bearings Scythe uses, plus a unique fan blade design that allows for extraordinary cooling even at a quiet maximum speed of 1500RPM. In our testing, the original Kaze Flex proved to be the best 120mm case fan on the market, and Scythe has only made it better with the Flex II, optimizing the fan frame to increase airflow and reduce turbulence!

    The Guru’s Tip

    You'll be mounting this fan to the front of the chassis to provide cool intake air to the motherboard, RAM, and CPU.

    Power Supply –

    SilverStone SX500-G

    $113
    To power up this build, we recommend this awesome SFX unit. It’s fully modular, offers Gold-rated efficiency, and at 500W, has more than enough power to support this system.

    The Guru’s Tip

    While the case we recommend can technically fit a full-size ATX power supply, going with this ultra-compact SFX model will make the PC so much easier to build and keep cool thanks to all the extra room it frees up inside, like the awesome cooler we recommend!
  • Thermaltake TH120

    CPU Cooler –

    Thermaltake TH120 Black

    $64
    Keeping a CPU cool in a high-powered, compact PC can be a challenge, but this liquid cooler has what it takes to get the job done. It is far superior to any low-profile air cooler, and it will match many of the best 120mm tower coolers. All that and it’s easier to install too!

    The Guru’s Tip

    Mount the radiator and fan to the rear of the chassis. There's plenty of space, as this case is perfectly designed for 120mm liquid cooling!
  • Microsoft Windows 11
    Click to Buy
    Operating System –

    Windows 11 Home (Download)

    $130
    Windows 11 take everything people loved about Windows 10, and then takes it to 11! It adds significant under-the-hood changes to make it faster and more secure, and of course, the interface is sleek too! This version can be instantly downloaded and installed from any USB stick with 8GB or more capacity. If you don’t have one handy, we recommend you pick up a fast USB 3.1 thumb drive to install it, which can then be re-purposed for backup or file transfer use.

    The Guru’s Tip

    It took Microsoft over six months to release Windows 11 to retail after initially making it available as an update to Win10 owners, but now that it's here, you definitely want the latest OS on your DIY PC!

    Razer BlackWidow V3 Clicky

    $100
    Razer has been in the gaming peripheral business a long time, and the BlackWidow is perhaps the most legendary bit of kit in history. It has practically defined the mechanical gaming keyboard market, and all the while has offered surprising value as well. That’s the story with the V3, which undercuts the other big names, while offering more style and more functionality. Razer’s Green mechanical switches deliver super-responsive tactile action. The keycaps are the high-quality Doubleshot ABS that enthusiasts pay extra for to fix other brands’ boards. And then there’s the stunning Chroma RGB effects that allow endless customization plus integration with countless games. In short, the BlackWidow is better than ever!

    The Guru’s Tip

    You can control the RGB effects of this keyboard using Razer's Synapse software.

    The Guru’s Tip

    We figure if you're building a small PC, it's very likely going to be tucked far enough away from you that using a wired headset will be a no-go!
