The ASUS ExpertCenter D501MER is a compact 15-litre mini-tower business desktop built around a 14th-generation Intel Core i5-14400 processor (10 cores, 16 threads, up to 4.7GHz, 20MB cache) paired with an Intel B760 chipset. It ships with 8GB of DDR5 U-DIMM memory and a 512GB M.2 2280 NVMe PCIe 4.0 SSD for fast boot and application load times, and includes a bundled 3.5" HDD assembly kit so an extra hard drive can be added on-site for bulk storage without buying a separate bracket. There's no optical drive, keeping the small chassis tidy, and connectivity covers Wi-Fi 6 (802.11ax, dual-band, 2x2) plus Bluetooth 5.4 for a fully wireless desk setup. Power comes from a right-sized 180W (80+ Bronze, peak 228W) supply. It's aimed squarely at office and SMB desks that need dependable everyday performance rather than discrete graphics -- Windows 11 Pro is preinstalled, and it comes complete with a wired keyboard and wired optical mouse plus 3-year on-site (next business day) support, making it a low-maintenance, ready-to-deploy fleet machine.
