The Best $3,000 Ultra-Extreme Mini-ITX Gaming PC Build – November 2022
Go Big, but Build Small!
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 $3,000 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.
This Month’s Build, Powered by Intel and Nvidia!
For November 2022, the $3,000 Ultra-Extreme Mini-ITX Gaming PC Build features the awesome new Intel Core i7-13700KF-core, 24-thread CPU, which lays down the law when it comes to gaming. It beats the prior king, Intel’s 12900KS, as well as everything in AMD’s lineup. When paired with a Z790 motherboard and 32GB of DDR5-6400 RAM, it will seriously rip! This setup is supporting a beast of a GPU, Nvidia’s GeForce RTX 3080 Ti 12GB!
Also on board is an amazingly-fast 2TB PCIe Gen 4-based solid-state drive and a 280mm liquid CPU cooler, which allows this mini-ITX rig to stay as cool as the big boys! Keeping the PC running is a 750W Platinum-rated power supply, and housing the system is the trend-setting Lian Li Q58 mini-ITX chassis, which comes in at 14.5 liters despite the capacity to hold all this gear, and more importantly, keep it all cool!

The DIY Build
Intel Core i7-13700KF$419With the 13700KF on the market, it’s game over for AMD! The 13700KF blows away Intel’s previous leader, the 12900KS, which was already unbeatable, and in doing so, drives a serious bargain at the extreme high-end of PC gaming performance. Offering up 16 cores, 24 threads, and the pumped-up cache and clockspeed, it’s the chip every serious gamer will want in their system!
This hot processor needs a great cooler, which is what we suggest later in this guide!
MSI MPG Z790I Edge WiFi$360This mini-ITX board has what it takes to support the latest socket 1700 Intel CPUs. It features a 10+1+1 phase VRM design, a 105-Amp power stage, and packs in a PCIe Gen 5 video card slot, triple PCIe M.2 slots (two being Gen 4), and 7 USB ports (1 being a Type-C 20Gbps Port). Also onboard is 802.11ax (WiFi 6E) wireless networking, Bluetooth, and 2.5Gb LAN.
While Z690 boards can support the 13th-Gen processor above, they will require updated firmware, while this Z790 board has it straight out of the box.
Video Card –
Zotac GeForce RTX 3080 Ti 12GB Trinity$1149For extreme performance, nothing less than the GeForce RTX 3080 Ti 12GB will do! This model offers up a sweet triple-slot, triple-fan cooler to keep it running at maximum boost!
At 318mm long, this card just fits within the case we recommend, which has a 320mm limit!
G.Skill 2x16GB Trident Z5 RGB DDR5-6400 CL32$220For the ultimate in speed, you must go with DDR5 RAM, but not just any DDR5 RAM, because you need high-frequency DDR5 to blow past DDR4 RAM performance. And that’s what you get with G.Skill’s TridentZ5 kit running at DDR5-6400 with timings of 32-39-39-102 at 1.40V. This is the real deal when it comes to DDR5 performance!
We've selected a DDR5-compatible motherboard that will easily support the ultra-high frequency of this kit!
Solid-State Drive –
WD_Black SN850X 2TB NVMe$230WD took its vaunted SN850 and endowed with even greater speed, creating the 850X. Powered by amazingly-fast NAND flash, and offering transfer speeds up to 7,300MB/s, it’s the one you want!
While you don't really need a drive this fast for gaming, in a system this good, you know you want it!
Lian Li Q58X4 Black$143Lian Li has taken its design expertise and one-upped the entire Small Form Factor case industry with the Q58X4. Coming in at just 14.5 liters, it’s impossibly-small for its capacity. It uses a sandwich-style layout, putting the GPU behind the motherboard, while making room at the top of the case for a liquid cooler up to 280mm in size to exhaust all the system’s hot air. Plus it combines mesh and glass panels in a modular format to provide both plenty of air intake and a great view of your high-end components. And take note: the X4 edition of this case includes a high-quality PCIe Gen 4-capable riser cable to ensure full bandwidth to the latest video cards!
This case can fit video cards up to 320mm long. We have confirmed that the model recommended in this guide is within that limit.
Power Supply –
Corsair SF750$160Offering a tremendous 750W of power output and Platinum-rated efficiency in an ultra-compact package, Corsair’s SF750 sets the standard for ultra-premium SFX power supplies!
While you can use a larger PSU in this case, we recommend the smallest possible unit to provide maximum airflow and cable routing space. Don't worry, this model has more than enough power!
CPU Cooler –
Corsair iCUE H115i RGB Elite$160For a hot-running processor, you need serious cooling, and this 280mm liquid cooler from Corsair has what it takes. The big 140mm AF-series fans use 9 heavily-swept blades to provide tremendous static pressure. That translates to fantastic performance, and that combined with its classy looks makes the H115i the perfect match for this system.
This cooler will act as an exhaust for the entire system - make sure to set it up with fans blowing up and out through the radiator! Also note that this model includes the Socket 1700 adapter required for use with Intel's latest processors!
Operating System –
Windows 11 Home USB$139Windows 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!
Microsoft took its sweet time launching the retail version of W11, previously limiting the release to upgrades for existing W10 customers. But it's here now, and this is definitely the OS you want on a PC running Intel's latest hybrid CPU architecture!
