At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.

The Dell OptiPlex 5090 SFF desktop delivers exceptional business computing performance with its 11th generation Intel Core i5-11500 processor (6 cores, 2.7GHz base), 8GB DDR4 RAM, and ultra-fast 128GB NVMe SSD storage. This compact small form factor design maximises workspace efficiency while providing enterprise-grade reliability and comprehensive connectivity options. Professionally refurbished by Reboot IT with Windows 11 Pro pre-installed and backed by our comprehensive 12-month warranty for complete confidence.
The 11th generation Intel Core i5-11500 processor represents a significant performance leap over previous generations, delivering exceptional responsiveness across demanding business applications. With six processing cores and intelligent Turbo Boost technology reaching 4.6GHz, this system handles complex Excel spreadsheets, simultaneous MYOB and Xero accounting sessions, and multi-user Teams video calls without performance degradation. The improved architecture provides 19% better performance per clock cycle compared to 10th gen processors, ensuring smooth operation even when running resource-intensive business software alongside multiple Chrome tabs and Outlook email management.
Storage performance transforms the daily computing experience through the SK Hynix BC711 NVMe SSD configuration. This enterprise-grade solid-state drive delivers sequential read speeds exceeding 3,200MB/s, enabling Windows 11 Pro to boot in approximately 8 seconds and launching Microsoft Office applications almost instantaneously. File transfers, database queries, and system updates complete dramatically faster than traditional hard drives, while the SSD's silent operation eliminates mechanical noise typical of conventional desktop systems. The 128GB capacity provides ample space for essential business applications, documents, and system files while maintaining optimal performance levels.
The small form factor design maximises workspace efficiency without compromising connectivity or expansion capabilities. Measuring just 29.2cm × 9.3cm × 29.2cm, the OptiPlex 5090 SFF fits comfortably under monitors, on shelves, or in compact workstation configurations. Despite its reduced footprint, the system provides comprehensive I/O options including multiple USB 3.2 ports, DisplayPort and VGA video outputs for dual-monitor setups, Ethernet connectivity, and audio connections. The vertically-oriented design promotes efficient airflow while the quiet cooling system ensures minimal workplace distraction during operation.
