Is $699 a fair price for this miniPC? Based on the Specs (i3-N300, 16GB LPDDR4, 4x NVMe Bays, 2.5GbE Port)

$699 i3-300 🤣 You can do much, much better in the $700 range. Look at just about anything in the GMKTec K line, for starters. Picking one at basically random, the NUCBox K12 Ryzen 7 H 255 with 32GB RAM/1TB SSD, Oculink and dual 2.5Gb NIC is currently $649. That will absolutely smoke an i3-300 perfor

Best Gaming Mini-PC for $500-$600?

I think the GMKtec K12 is probs good value at $500 (Ryzen 7 8745HS CPU, Radeon 780M iGPU - 32gb RAM, 500GB SSD) vs competitors who have soldered ram and less expandability. The K12 has three SSD slots and you can replace the RAM. Plus it has an OCulink port so you can plug a dedicated GPU to max gam

GMKtec Gaming Mini PC AMD Ryzen 9 8945HS (Turbo 5.1GHz) 32GB DDR5 2TB SSD, Computers PC Oculink, Dual NIC LAN 2.5G, WiFi 6, USB3.2, USB-C 4.0, BT5.2, DP, HDMI, Dual Fan Nucbox K11

Yes but what's your use case? If will use with egpu thru oculink, and dont really need ryzen 9 power, can go with GMKtec K12 instead as it has the oculink port at the back.

Kid’s First PC, Linux Mint & Minecraft, Suggestions?

With the way prices are right now, if you don't already have some laptop RAM sticks laying around to drop into a barebones unit, AOOSTAR's MACO 6850H is pretty enticing as a budget option with a solid iGPU. Available for US 300 ish on their website with no SSD installed but the 24GB RAM is soldered

Any experiences on Linux compatibility for GMKtec NucBox K12 AMD Ryzen™ 7 H 255 Mini PC ?

I got my K12 and am using it for over 2 weeks now, I must say its quite good and no issues whatsoever, I installed Linux Ubuntu latest version on it directly and everything running smoothly without any issues, I got mine barebone, got my own RAM 48GB and 4TB. The CPU Ryzen 7 H 255 works great and qu

Gmktec k8 plus or k12

The third M.2 slot on the K12 is awkwardly placed, there's a capacitor right underneath it so you don't really have space to put a heat sink on your NVME in that slot if that's a thing you're wanting to do. K12 is also down to a single USB4 port vs the two on the K8+ for whatever reason. I went with

I know absolutely nothing about computer specs. I'm wanting a minipc for PS2 Emulation. Is this enough power to do so?

Get yourself a mini pc with an AMD Ryzen H255 (aka 8745hs). It has 8c/16t that goes up to 4.9Ghz. AVX512 support which is essential for emulation and a really powerful iGPU (780m). It is capable of not obly ps2 emulation but also ps3 emulation, switch emulation ... In other words, it'll be able to e

Good mini pc (sold on amazon) that allows for a modern dedicated graphics card to be installed?

I'm running a gmktec k12, it has a dedicated oculink port for external gpu setup. I tested with my old gtx1060 and it works fine, no troublesome setup. Buy egpu dock + psu, 650w is generally fine unless you're using 3090, 4080, 4090, etc. since 650w psu won't have enough power cables. Install nvidia

Get a GMKTEC k12 zero Bluetooth or WiFi issues it's a little power house built tough out of metal.

My daughter liked the spinning fans a little bit too much

Ok so I did a little comparison with my desktop PC at 2K res (this screen is in Polish but you'll figure out). This is of course not the highest fps achievable, with a little tweaks it can reach close to 200fps. Gmktec K12 16GB RAM ddr5 + 4070 eGPUvsDesktop 13400F 32GB RAM ddr4 + 4070 and im in shoc
