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

GMKtec K8 plus vs K12 vs K16?
Its all about processors in 3 different builds. The K16 7735HS is a rebadged Rembrandt 6800HS from 2022. The K12 H 255 is a lower quality 260/8845HS for the Chinese market while the K8 Plus 8845HS is fully authentic and supported by AMD. When I was searching for my mini last year I wanted more perfo

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

What's your 'I can't believe I self-hosted that' service?
Honestly it's working good, a bit rough around the edges. I built it because I really don't like Android. The lack of control, software support abandonment, etc, have driven me to work towards eradicating Android from all my devices. So atm we have these Mini PCs, they were £160 no RAM no SSD. Beast

Beelink S13 which sustained CPU temp okay?
any temperture is ok. modern computers are designed to slow down the processor if it becomes to hot and if it gets too extreme even after that it will simply turn off the motherboard. 75 degrees celsius is perfectly fine. mine occasionally run at up to 95 degrees, which is still within their designe

Gmktec K12
Things have changed last decade, mini pcs performances are close to desktop pc, with the bonus mini pcs use a fraction of the energy of a desktop pc. My k12 is left switched on 24/7 it goes to sleep when not in use in windows11, no need to worry about energy prices anyhow. Check hot uk deals for gmk

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.
