9th Gen i9 Mini PC - €599.74 on AliExpress
(€ 488.49 / AU € 944.36)
This small but powerful workstation packs a punch thanks to the inclusion of an Intel Core i9-9880H processor. At that price, it also comes with 8GB of RAM and a 128GB SSD, and you won't find a cheaper equivalent on the market. Sold by Shenzhen Helor Cloud Computer Store via Aliexpress, the device is powered by an Intel Core i9-9880H processor, which has eight cores, 16 threads and uses 14nm lithography. With a base frequency of 2.3 GHz and a cache of 16 MB, it has a TDP of 45 W and is based on an Intel UHD Graphics 630 graphics processor. For context, the cheapest Core i9 processor we could find costs around € 520, barely cheaper than the entire workstation. This thin client can occupy up to 64GB of DDR4 memory, supports up to three solid-state drives, and uses 90W of power. It also has two video ports, five USB ports (including Type C), a GB Ethernet jack, and an audio port. At 15 x 14,6 x 6,65 cm, it's compact enough to be easily transported.
