Serious 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!
Today’s Build, Powered by Intel and Nvidia!
For December 2022, this build takes advantage of a massive price cut on Intel CPUs, specifically the Intel Core i5-12600KF, a 10-core, 16-thread CPU that offers incredible power for the price. It’s supporting the Nvidia GeForce RTX 3070 8GB, the most powerful GPU you can fit in this system.
Also on the build list is 16GB of speedy DDR4-3600 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 that maximizes the system’s cooling performance. Finally, feeding this system is a quiet, efficient 650W power supply. Learn more about building in the SG16 case in our full review below.

The DIY Build
Intel Core i5-12600KF$228 The Guru’s Tip
This CPU does not come with a cooler, so make sure to grab the liquid cooler we recommend later in this guide!
ASRock B660M-ITX/AC$120 The Guru’s Tip
Note that this board does not support overclocking. While the unlocked processor we recommend will only run at stock speed, it will still be very fast!
Video Card –
Zotac GeForce RTX 3070 8GB Twin Edge$503 The Guru’s Tip
At 9.1" long, this card will easily fit in the case we recommend, which has 10.8" of clearance. It's actually the most powerful GPU of any kind that will fit in this system!
G.Skill 2x8GB Ripjaws V DDR4-3600 16-19-19$60 The Guru’s Tip
The kit has the absolute perfect combination of frequency and timings for the Intel DDR4-based platform!
Solid-State Drive –
WD Blue SN570 1TB NVMe$70 The Guru’s Tip
Remember to install this drive before you install the motherboard in the case!
SilverStone SG16$94 The Guru’s Tip
This case is also available in a sleek white finish, which is listed on the same product page.
Case Fan –
Scythe Kaze Flex 120mm Fan$14 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 SST-SX650-G$121 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 –
DeepCool LS320$80 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!
Operating System –
Windows 11 Home USB$139 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!
The 27" 2560x1440 Gaming Monitor –
HP X27q$284 The Guru’s Tip
This monitor will let you get the most out of your new high-end gaming PC!
The Budget Gaming Keyboard –
Corsair K55 RGB Pro$50 The Guru’s Tip
You can control the RGB effects of this keyboard using Corsair's iCUE software.
The Pro Gaming Mouse –
Razer Basilisk X HyperSpeed Wireless$35 The Guru’s Tip
Whether you're using your PC from a desk or the couch, this is the perfect mouse!
The Budget Wireless PC Headset –
SteelSeries Arctis 1 Wireless$100 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!
