Best $2,500 Ultra-Extreme Mini-ITX Gaming PC Build

If you're looking for a no-holds-barred extreme Mini-ITX Gaming PC Build in a sleek, compact chassis, this is the one for you! Our $2,500 Ultra-Extreme Mini-ITX Gaming PC Build might be dwarfed by standard towers, but it can easily keep up with them thanks to its truly extreme components. 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 January 2020, this build jumps into a new home, the In-Win A1 Plus case. It's clean and fresh, the perfect thing for a new decade! But it's not all about looks with the $2,500 Ultra-Extreme Mini-ITX Gaming PC Build. Inside it's packing the incredible Ryzen 9 3900X, a 12-core, 24-thread powerhouse. This CPU is what makes this mini PC a true beast. It's cooled by the unmatched Scythe Fuma 2, the best air cooler for a compact build. On graphics duty is the GeForce RTX 2080 Ti 11GB video card, which will easily drive all your games at 4K. With that said, being "Ultra-Extreme" doesn't begin and end with the CPU and GPU. That's why this build also features an ultra-fast PCIe 4.0-based 1TB solid-state drive and a towering 32GB of high-speed DDR4-3200 RAM with RGB effects. The build is powered by an ultra-compact 650W Gold-rated power supply, included with the case. At just 22 liters, it's truly compact, and yet it fits the very best components available.

The $2,500 Ultra-Extreme Mini-ITX Gaming PC Build - January 2020

  • CPU:

    AMD Ryzen 9 3900X

    The AMD Ryzen 9 3900X has stolen the lead as the best overall CPU available at its pricepoint (when it's actually available at MSRP!). With 12 cores and 24 threads, it's a workstation CPU in everything but name, yet has fantastic gaming performance thanks to its high boost clocks.

    The Guru's Tip:

    This CPU is selling out frequently, so don't hesitate if you see it in stock!

  • Motherboard:

    Gigabyte X570 I AORUS Pro WiFi

    This great board features dual M.2 slots (one in front, one underneath), built-in 802.11ac wireless networking with Bluetooth, and six USB ports, including a Type-C port.

    The Guru's Tip:

    Keep in mind that the video ports on this board won't function when used with a Ryzen 7 processor, as it doesn't have built-in graphics.

  • Video Card:

    MSI GeForce RTX 2080 Ti Ventus GP

    For this build, we recommend nothing less than the king of the hill: the RTX 2080 Ti 11GB! This card will absolutely blow through any game, and can even handle extreme Ray Tracing effects in the latest games.

    The Guru's Tip:

    Please be careful about substituting in other RTX 2080 Ti models - most will be too wide to fit in the case since they typically take up 3 slots.

  • Memory:

    Corsair 2x16GB Vengeance RGB Pro DDR4-3200

    To get the most out of this system, you want high frequency DDR4, and we recommend this high-speed DDR4-3200 kit in a 2x16GB configuration, which allows you to seriously max out performance and capacity. It will help eliminate any bottlenecks in getting data to your CPU.

    The Guru's Tip:

    This kit offers up some really sweet RGB effects, which you can control via the motherboard or Corsair's iCUE software.

  • Solid-State Drive:

    Sabrent 1TB Rocket PCIe 4.0

    You want to take advantage of the awesome PCIe 4.0 bandwidth provided by the X570 motherboard in the $2,500 Ultra-Extreme Mini-ITX Gaming PC Build, right? Then of course you want to go with the Sabrent Rocket PCIe 4.0, which is the fastest drive ever released, with read/write speeds of up to 5,000MB/s!

    The Guru's Tip:

    This M.2 drive will slot right into the motherboard - no cables required!

  • Case:

    InWin A1 Plus White w/ 650W PSU

    This awesome 22-liter case allows you to max out an ITX build while still remaining very compact. And thanks to its beautiful exterior and sweet RGB lighting, it's also a work of art! It includes dual 120mm fans, one for intake, one for exhaust.

    The Guru's Tip:

    This case even includes a 650W Gold-rated power supply pre-installed - no, we didn't forget the power supply in this build!

  • CPU Cooler:

    Scythe Fuma 2

    Get the ultimate in air cooling from the Fuma 2, a powerful dual-tower cooler that just so happens to fit easily on an ITX motherboard.

    The Guru's Tip:

    This is what will allow your 3900X processor to really fly!

  • 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 USB 3.0 version of W10 will install in under 5 minutes!
