Review: Powerful Compute in an Efficient Package - Proxmox Cluster Node - I've always been one to buy decommissioned enterprise gear for my homelab but I had a need to add an additional Proxmox cluster node in the house, around people, so I wanted something more human friendly. Looking over all the options, MINISFORUM seemed to offer a wide range of combinations of technology and the most difficult decision was which processor/ram/architecture I wanted. I ended up choosing the NAB9 w/ Core i9-12900HK specifically for the Cores/Threads and clock it ran at with 32gb of RAM. This should be plenty to play host to infrastructure VMs to maintain HA. I am using the 2.5gb LAN ports as one for the VM network and one for the Storage network. With how fast it is, you can't even tell that the VM's disks are in another building on a NAS when it serves a site from the VM on the NAB9. It boots very quickly and is completely silent and it doesn't seem to generate much heat, if any. In my case, I unboxed it, plugged in the KVM and network, connected my Proxmox USB Bootable installer, and went from new to cluster member in under 30 minutes making it very easy to use! I do have to bring up one small issue. A few weeks after I had it up and running it suddenly turned off and wouldn't turn back on. I know this sounds bad but it's actually a testament to how supportive MINISFORUM is. I opened a support ticket and had an email response within hours, not days! We performed the troubleshooting steps and emailed back and forth that next day before I was given the greenlight for a repair. The speed of their service and support was way beyond my expectations! I sent in the NAB9 and counting travel to there, from there, and fixing it, was 5 days. Under 1 week and I had the machine back and up and running! Since the repair I wanted to wait a bit to make certain everything stayed good before I left my review. But now it's time. I've had the NAB9 running 24x7 since I got it back several months ago and it's been amazing. So much so, that I forget I have it running in the house. I haven't had to do any fiddling or anything. It's great and just works. I feel that I can confidently say now that it's high quality and an excellent value for how much compute you get for the price. Thank you MINISFORUM, this device has filled a specific need for me perfectly.
Review: An Impressive Mini PC - After a week of using my new Minisforum M1 Pro-285H, I can say that I am pleased. It is an impressive mini PC that combines aesthetics, easy setup, and powerful performance suitable for a variety of tasks. It boasts a sleek, premium looking, compact and sturdy aluminum alloy unibody chassis, which is easily accessible by removing just four screws, should I need to add a second NVMe SSD or more DDR5 RAM. It also came pre-installed with Windows 11 Pro, which made the setup a plug-and-play experience requiring little effort beyond connecting my peripherals. With its Intel Core Ultra 9 285H processor and integrated Intel Arc 140T GPU, it delivers exceptional performance for my daily computing and creative work needs, handling my photo and video editing applications smoothly. Last, but not less important, the fan cooling system is efficient and silent enough to ensure a quiet working environment. With my experience so far, I definitely recommend the Minisforum M1 Pro-285H mini PC.

### ⭐⭐⭐⭐⭐ Incredible deal!
*by C***N on December 27, 2025*

To be clear, this review is for the Minisforum X1 Lite-255 with 64GB of RAM and 1TB SSD. Not sure why Amazon is mislabeling this review under a different product on the same page. I think I am done with full size computers. It's hard to believe just how fast these mini PCs have become and when they are built with quality RAM and storage and have great cooling while costing less than a typical full size computer, I can't find any reason to back. This little guy has 8 cores and 16 threads and nearly hits 5Ghz while remaining nearly silent and having no heat issues even on the most intense tasks. The RAM and SSD are made by Crucial and are not the generic 'cheap stuff' other manufacturers often use to increase their own profit. The case is entirely plastic. This is a good thing because metal cases block WiFi and Bluetooth signals to a point. With plastic, WiFi and Bluetooth range are fantastic on this little guy! I also appreciate that Minisforum sells a version of this exact mini PC without any RAM, SSD or operating system. These days, those components can double the price of a computer. So if you already have your own, its less waste and a big cost savings if you are a DIY type. I love this has USB4 and it has an OcuLink port. By default, with the model I ordered, it has a 1TB NVMe drive that runs at top Gen4 speeds (see photo) with no heat issues. Next to it is an empty M.2 slot for expanding the storage. Alternately, you can use the OcuLink adapter included in the box to install in the empty M.2 slot if you prefer to use it for an eGPU. Your choice and it's not sold separately. It's included at no extra cost and can be removed if you change your mind later and want to use the second M.2 for storage later on. While this mini OC can play plenty of games as-is with it's built-in AMD Radeon 780M graphics, the sky is the limit when gaming with an external GPU using OcuLink. This little guy does my photo editing and my video editing with ease and I can't get over how cool and quiet it stays! The RAM can be upgraded. It is NOT soldered in like other models. Same is true with the WiFi/Bluetooth adapter (a MediaTek) and the aforementioned NVMe SSD. Mine came with Windows 11 Pro 24H2. I updated it to 25H2 and update the AMD Adrenlin and chipset drivers and, again, I find it hard to believe you get so much in every category of computing and pay so little for it! The CPU in here has no NPU (no AI processor) so I also save money there for something I have no use for. I expect Minisforum to be a household name in a few years. They have been around since 2018 and I have been very impressed with their products, prices, warranty and support so much, I have been buying from them ever since with each year bringing new designs and more performance and functionality with each new generation. Minisforum just makes these mini PCs with so much unique ingenuity that many of their models have no equal competitors (yet!) So, for whatever it's worth, until you get one in your own hands and see for yourself, I don't know the words to express my happiness with this purchase!
