Is it for you?
A bare-bones mini PC kit in ASUS's NUC 15 Pro line with an Intel Core Ultra 5 225H processor, dual Thunderbolt 4, 2.5G Ethernet and Wi-Fi 7, shipped with no memory, storage or operating system for buyers who want to choose their own parts.
Choose it if these matter
- Bare-bones kit format with two user-accessible M.2 slots and dual SO-DIMM slots (up to 48GB), a good starting point for a Proxmox or self-built home server
- Supports Windows 11, RedHat Enterprise Linux and Ubuntu 24.04 LTS out of the box, with no preinstalled OS to pay for
- Compact 0.58 kg chassis with a VESA mount included, quiet enough for a desk or shelf
Skip it if these rule it out
- No memory, storage or OS included: budget for RAM, an SSD and an operating system on top of the kit
- The Core Ultra 5 225H is a mid-tier CPU; heavy multi-VM labs may want the Core Ultra 7 255H or 265H SKUs
- No Amazon listing is linked from ASUS's own where-to-buy list for this model, so buying it means searching for the exact model
- Graphics and memory must be matched per ASUS's notes: the Arc iGPU requires 2 x SO-DIMM
Good for: Homelab · Home office · Media server
