Gigabyte AORUS Master 18 (AM8H)
Flagship desktop-replacement

The 18" big brother: an overclockable 175 W RTX 5090, a Mini LED panel, and extreme expandability (up to 128 GB RAM and 6 TB of SSD across 3 slots) plus Thunderbolt 5. Independent reviews were thin at research time, and at 270 W it will run hot and loud — a true desktop replacement.
