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 desktop while packing in the same performance. That’s 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 big towers that cost the same or more!

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

For August 2022, this build gets a number of upgrades. One thing that remains the same is the AMD Ryzen 5 5600X 6-core, 12-thread CPU. It’s supporting a beast of a GPU, the GeForce RTX 3070 8GB, which will have no trouble keeping up with the latest games, and has recently dropped in price, making it a perfect fit for this system’s budget.

Also on the build list is 16GB of speedy DDR4-3600 RAM, along with a quick 1TB PCIe solid-state drive. The build comes together in the compact SilverStone SG16 chassis and uses a new Noctua dual-tower cooler that fits hand-in-glove in the case, almost as if they were designed for each other! It outperforms the liquid cooler we previously recommended, while being far quieter! Finally, feeding this system is a quiet, efficient 650W power supply, an upgrade from the 500W unit we use to recommend. Learn more about building in the SG16 case in our full review below.

The DIY Build

  • CPU

    AMD Ryzen 5 5600X

    AMD’s Zen 3 architecture made a huge splash in the PC industry. Beating Intel on a clock-for-clock basis for the first time in decades, and with far lower power consumption, the Ryzen 5 5600X is the perfect CPU for this build. And it brings along with it an advanced yet cost-effective platform, which will provide upgrade potential down the line should you wish to drop in an even more powerful CPU.
    The Guru’s Tip

    This CPU comes with a cooler, but for higher performance and lower noise levels, go with the premium model we recommend later in this guide.

  • Motherboard

    Gigabyte B550I Aorus Pro AX

    This board has all the features you need for an ultra-high-end build, despite its reasonable pricepoint. It features dual M.2 PCIe slots, with the top slot supporting full Gen 4 speed, 2.5Gbps LAN, built-in 802.11ax wireless networking with Bluetooth, and six USB ports, including a Type-C port.
    The Guru’s Tip

    The video ports on this motherboard will not be operational when used with the CPU above. But don't worry - you'll be using an add-in video card anyway!

  • Video Card

    Zotac GeForce RTX 3070 8GB Twin Edge

    Zotac’s RTX 3070 Twin Edge offers fantastic performance and great cooling with very low noise levels. While the 3070 was out of reach for a long time, it can finally be yours at a great price!
    The Guru’s Tip

    At 9.1" long, this card will fit easily in this build, which has a limit of 10.8".

  • Memory

    Patriot 2x8GB Viper Steel DDR4-3600 17-19-19

    To get the most out of DDR4 memory, you want high frequencies, and Patriot’s Viper Steel 2x8GB DDR4-3600 RAM delivers! DDR4-3600 is the sweet spot in terms of price/performance, and this kit has tight 17-19-19 timings to back up the high frequency!
    The Guru’s Tip

    This high-speed kit is a great match for the AMD platform!

  • Solid-State Drive

    WD Blue SN570 1TB NVMe

    WD knocked it out of the park with its high-performance yet bargain-priced SN570. 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 3500MB/s and write speeds of 3500MB/s. Note that you’ll need a jeweler’s-type screwdriver to affix it.
    The Guru’s Tip

    Remember to install this drive before you install the CPU cooler!

  • Case

    SilverStone SG16

    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.

  • Case Fan

    Arctic P12 PWM

    Want to cooler your system without a noise penalty? Look no further than the excellent P12 PWM from Arctic. It offers fantastic performance at low noise levels, and comes in at a shockingly-low price, despite a market-leading 10-year warranty.
    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

    EVGA Supernova 650GM

    This high-quality SFX-class power supply offers 650W of Gold-rated power, fully-modular cables, and and impressive 7-year warranty, backed by EVGA’s legendary customer service. You simply cannot go wrong with this well-priced unit!
    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!

  • CPU Cooler

    Noctua NH-D12L

    This unique cooler is custom-tailored for compact systems. At just 145mm tall, it’s the shortest cooler on the market to feature a 120mm fan, and this is no ordinary 120mm fan – it’s a specially-designed version of the NH-A12x25, the best cooler fan on the market!
    The Guru’s Tip

    Honestly, this is simply the best cooler for the SG16 case, which we know because we've tested them all! It will significantly outperform a 120mm liquid cooler! One builder's tip: connect the power supply's modular 8-pin EPS cable to the motherboard before you mount this cooler, because it's impossible to do so once the cooler is in the case.

  • Operating System

    Windows 11 Home USB

    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!
    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!

Optional Products

  • The 27" 2560x1440 Gaming Monitor

    HP X27q

    HP has taken over the value high-end gaming monitor market with the X27q. Didn’t think you could get value in a high-end monitor? Think again! The X27q offers all the specs you could want: a 27″ 2560×1440 IPS panel capable of a 165Hz refresh rate, enhanced with FreeSync Premium frame-syncing technology. Previously, you couldn’t get anything but an inferior TN panel for this price. The X27q even has a height-adjustable stand, which we consider critical for a high-end monitor, making this a flat-out winner!
    The Guru’s Tip

    This monitor will let you get the most out of your new high-end gaming PC!

  • The Pro Gaming Mouse

    Razer Basilisk X HyperSpeed Wireless

    Offering cutting-edge performance, there’s nothing like the Basilisk X for anywhere near the price. Ultra-sensitive sensor, Razer’s awesome HyperSpeed wireless system, and perfect ergonomics. It’s a great mouse!
    The Guru’s Tip

    Whether you're using your PC from a desk or the couch, this is the perfect mouse!

  • The Budget Gaming Keyboard

    Corsair K55 RGB Pro

    Pick up a great keyboard at a great price with the K55. It offers IP42-rated dust and spill resistance, zoned RGB backlighting, dedicated macro and media keys, plus quiet keys with a tactile bump to provide great feedback with low noise levels!
    The Guru’s Tip

    You can control the RGB effects of this keyboard using Corsair's iCUE software.

  • The Budget Wireless PC Headset

    ‎SteelSeries Arctis 1 Wireless

    SteelSeries has made a name for itself in the gaming headset world with its no-nonsense focus on performance. The Arctis 1 follows in this tradition with high-end drivers, lossless 2.4 GHz wireless for ultra-low latency wireless connectivity on both PC and PS4/PS5, a detachable bidirectional microphone, and 20 hours of battery life.
    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!
