Size: 32GB+1TB/Ryzen 7 7730U
After my old i7 PC reached its limits, I decided on the KAMRUI E3B after thorough research – and I am thrilled. Even when unpacking, you can tell that quality was a priority: a sturdy, high-quality case, precise connections, and a compact size (13 × 13 × 4 cm) that looks great on any desk. The scope of delivery includes everything you need for an immediate start – even accessories for installing an additional SSD. Particularly commendable: the expandability. The RAM can be upgraded to 64 GB, M.2 SSDs up to 2 TB are possible, and there is a port for a second 2.5" SSD/HDD. In practical use, this mini PC is convincing with its impressive performance. Equipped with an 8-core, 16-thread AMD Ryzen 7 7730U, 1024 GB of memory, and a 512 GB SSD, it provides a smooth working experience—whether for office work, multimedia, image processing, or 3A games. Even when running multiple demanding applications simultaneously, it operates stably and without delay. Even when it comes to connection variety, the E3B leaves nothing to be desired: RJ45 Gigabit LAN, HDMI 2.0, DisplayPort, USB-C, USB 3.0/2.0, and Audio In/Out – ideal for office, home server, or multimedia setup. The setup is simple, Windows was pre-installed and ready to use immediately. Particularly noteworthy is the excellent customer support: via WhatsApp, I received competent help with an update problem within a few minutes – fast, friendly, and solution-oriented. Temperature and noise levels are also convincing: even under load, the mini PC remains quiet and pleasantly cool. Conclusion: The KAMRUI E3B is a powerful, quiet, and versatile mini-PC with first-class craftsmanship, modern features, and excellent support. A clear purchase recommendation for anyone looking for a compact, reliable, and expandable computer. ... show more

  • Tiny but powerful, prefect for home media server Tiny but powerful, prefect for home media server
Size: 32GB+1TB/Ryzen 7 7730U
The PC comes well packaged. It comes with a USB-C power supply, an HDMI cable, and a mounting plate with screws for mounting. I really like that they thought about mounting options and provided the plate and screws out of the box. The PC comes with Windows 11 pre-installed, and it boots up directly out of the box. A quick piece of advice: follow the manufacturer's tip to not configure the network immediately, otherwise it will take some time to boot and download all the updates. It also comes with a SATA extension cable for adding extra SSDs or HDDs. This computer has all the peripherals I need, and one great thing is that it supports two Ethernet ports—one is 2.5GbE, and the other is standard GbE, which is perfect for my intended use as a home media server. It has a fan, but it rarely turns on, so it is almost silent. It is powerful enough for local transcoding and encoding/decoding high bit-rate content. When not in use, it consumes barely any power. Highly recommended! ... show more
