Fanless operation sets the Elo E128604 apart within the X-Series line, making it suited to noise-sensitive retail and hospitality environments where a quad-core Intel Celeron running at 2.41 GHz handles POS workloads without a cooling fan. The terminal ships with 2 GB of DDR3 SDRAM and a 320 GB SATA hard drive, running Windows 7 Professional x64 with SP1. Its 15-inch LED touchscreen is paired with IntelliTouch surface acoustic wave technology, and connectivity spans USB, powered USB, serial, Gigabit Ethernet, wireless LAN, and a dedicated cash drawer port. The black chassis measures 13.7 in tall, 14.4 in wide, and 2.6 in deep at a weight of 10.60 lb, and the unit is backed by a 3-year limited warranty.
