Corebox Pro Desktop Mini Computer

Low Fan Noise Gaming Desktop Under $400

The Core box Pro offers a lot of features we don’t normally see for this price group, Thunderbolt 3 support, Intel Wireless AX201 Wifi 6 chip with BT 5.1, [email protected] HDMI support, and Display port 1.4A (4k60) with the thunderbolt port means it can run 3 displays simultaneously.

The SSD inside is a 256GB Toshiba NVMe with good speeds and we can also add a 2.5″ drive for expanding our storage capacity. The Core box comes with a 3733Mhz max DDR4 RAM spec with the odd amount of 12GB which is completely soldered into the motherboard like the Intel AX200 Wifi 6 chipset.

Sadly only the storage is the upgradable component with this model which is one of the few cons. The other one being the fact it has the Core i3 1005G1 10th Gen 10nm Intel chipset. This is good for general computing and everything does feel quick and snappy until you try to edit a 4k video or play a modern game.

The Corebox has Intel UHD G1 graphics which while a step up over the typical UHD 620 graphics with its 32 execution cores isn’t really that powerful at all a low-end GPU.

However, you can play light older games like Counter-Strike or GTA V at 720 with playable frame rates. It comes with a 256GB Toshiba NVMe drive these are the speeds. This Mini PC ships with Windows 10 Home and it’s activated via a digital license SLC which is part of the bios.

The cooling in this mini pc is overkill for the Core i3 with a max 3.4Ghz turbo. This cooler could handle the likes of a quad-core 8th or 10th gen 28W TDP chip without even hitting the max RPM.

This corebox can run Windows 10 desktop at 4k120hz which matches LG CX’s 120hz refresh rate. If you plan to run 4k120 make sure you update the Intel GFX drivers and use a top-quality HDMI 2.1 cable.

Pros and Cons


  • Big upgrade over the original Corebox with a super slow 5th Gen Core i3
  • Very good cooling and fan noise
  • HDMI supports up to 4k 120hz (8bit)


  • No upgrades apart from storage could be swapped for a faster larger NVMe
  • Weak Core i3 dual-core with 4 threads.
