If you want a no-holds-barred extreme PC without the bulk, this system is the one for you! This system might be dwarfed by standard towers, but it can absolutely go go toe-to-toe with them. And amazingly, there is virtually no price premium for getting a system of this caliber down to a portable size, making this PC a pretty good value too.

For November 2018, this build is better faster than ever, thanks to the release of the incredible new Intel Core i7-9700K eight-core processor and the new Nvidia GeForce RTX 2080 8GB video card. This combo will provide mind-blowing gaming performance, but this build is ultra-extreme in other ways too. It sports the class-leading Samsung 970 Pro 1TB solid-state drive, 32GB of high-speed DDR4-3200 RAM, and a 700W Platinum-rated power supply. Cooling comes courtesy of a slimline 120mm CPU cooler, and the build comes together inside an ultra-slim, ultra-sleek chassis. Indeed, the SilverStone FTZ01-E case, with its aluminum unibody design, truly stands out in terms of aesthetic appeal. To learn how to build up this system, check out our review of the SilverStone RVZ01-E, which is identical to the FTZ01-E other than the exterior material.

The $2,500 Ultra-Extreme Mini-ITX PC - November 2018


    Intel Core i7-9700K

    The new 9700K is the new ultimate gamer's chip. It offers eight cores that can be overclocked to 5GHz, providing simply unbeatable performance when it comes to gaming.

    The Guru's Tip:

    While this chip does not have Hyperthreading, that's actually a benefit for games, which don't work well with virtual cores.


    Asus ROG Strix Z390-I Gaming

    This tiny board truly has it all: top-of-the-line Realtek ALC1220 audio, dual full-length M.2 slots (one in front, one on the rear of the board), Intel wired networking, 802.11ac wireless networking with Bluetooth, DisplayPort, HDMI, and seven USB ports, including a USB 3.1 Type-C port.

    The Guru's Tip:

    The 9700K CPU requires a Z390 motherboard like this one in order to boot. Z370 do not support the 9700K out of the box.

    Video Card:

    EVGA GeForce RTX 2080 XC Gaming 8GB

    You want 4K gaming capability? The 2080 will bring it! Released in late-September 2018, it edges past the previous king-of-the-hill, the GTX 1080 Ti, despite lower power use. Note that most RTX 2080 models will not fit in this build - they are too wide (2.5-3 slots wide). This model sticks to the standard 2-slot form factor.

    The Guru's Tip:

    The RTX 2080 offers slightly better performance in most games versus the GTX 1080 Ti, while also adding Ray Tracing capabilities for future game releases.


    Corsair 2x16GB Vengeance LPX DDR4-3200 White

    To get the most out of your Core i7-8700K, you want high-frequency DDR4 memory. For the Ultimate ITX Gamer, we go with ultra-high speed DDR4-3600 in a 2x16GB configuration, which gives you both tremendous speed and mind-blowing capacity. 

    The Guru's Tip:

    This is in fact the tallest RAM kit that will fit in this build - please don't go with RGB-lit modules, as they will not fit under the CPU cooler.

    Solid-State Drive:

    Samsung 970 Pro 1TB PCIe M.2

    For an extreme ITX build, nothing less than the best PCIe drive will do, and the benchmark by which all others are judged is the 970 Pro 1TB. Samsung has simply blown the competition out of the water with this drive. And thanks to a massive price war in the SSD market, this drive has already dropped $100 since its release!

    The Guru's Tip:

    Note that you'll need a jeweler's-type screwdriver to install this into one of the motherboard's M.2 slots, and we recommend you use the top-mounted slot for better cooling.


    SilverStone SST-FTZ01S-E

    This awesome case from SilverStone brings equal doses of style and class to the ITX arena. Featuring an aluminum unibody frame and an ultra-slim profile, it looks better than any other ITX case on the market. It even comes with two slimline 120mm fans, which we recommend you install above the video card as intakes.

    The Guru's Tip:

    While silver looks stunning, this case is also available in matte black.

    Power Supply:

    SilverStone SX700-LPT

    While the case recommended above can actually squeeze in an ATX power supply, a smaller SFX-class unit is a much better fit. Our pick: the awesome Platinum-rated SX700, which is incredibly powerful and incredibly-quiet. Read all about it in our hands-on review!

    The Guru's Tip:

    Note that you'll need to use the SFX-to-ATX adapter listed below to mount this small power supply in the case.


    SilverStone RL-PP08B Bracket

    This is the adapter you'll need to fit the power supply listed above in the FTZ01-E chassis.

    The Guru's Tip:

    Once you've mounted your PSU in the case using the adapter, we know you'll thank us for saving you the headache of trying to squeeze an ATX model in!

    CPU Cooler:

    SilverStone NT06-PRO-V2

    Keeping a CPU cool in a compact case is always a challenge, but this awesome air cooler from SilverStone is up to the challenge. 

    The Guru's Tip:

    This is in fact the largest cooler that will fit in the FTZ01-E case. It's 82mm tall, and the case has just 83mm of clearance!

    Operating System:

    Microsoft Windows 10 Flash Drive

    Windows 10 wipes away all the bad memories left behind by Windows 8, improving enormously on the user interface, and bringing with it some important performance tweaks under the hood.

    The Guru's Tip:

    This is the USB 3.0 version of W10, which loads in under 5 minutes!

Optional Components

    CPU Cooler:

    Noctua NH-L12S

    As configured above, the Ultra-Extreme ITX System is designed for maximum performance. If your preferences run more towards silence, swap the SilverStone cooler out for the awesome Noctua NH-L12S. While its ultimate cooling capacity is a bit lower due to a thinner heatsink, it's far quieter, especially at idle, while also being much easier to install.

    The Guru's Tip:

    The NH-L12S is perfectly capable of cooling a stock Core i7-8700K. The only time it might potentially limit performance is under extreme overclocking.


    SilverStone SST-RVZ03B

    Want a little more flash from your extreme ITX PC? Then go for SilverStone's RVZ03. Built on the exact same frame as the FTZ01-E, it trades the latter's aluminum cladding for a steel exterior, but adds RGB lighting that can be controlled via the motherboard we recommend!

    The Guru's Tip:

    This model is also available in a sleek white finish.

    The 35-inch Widescreen Monitor:

    Acer Predator Z35P

    Get the most out of your new gaming rig with this sweet high-refresh rate G-Sync monitor from Acer. Offering a huge 35", 3440x1440 panel running at up to 120Hz, this is the ultimate high-end gaming mointor. And with G-Sync, you don't notice any hitching or lagging, because the frames displayed will always sync with the frames delivered by the GPU.

    The Guru's Tip:

    Note that there a number of other widescreen monitors top out at a resolution of 2560x1080. Avoid them at all cost!
