Product/Model Name: ALEXON / NAS-453-G CPU: Intel® Celeron® J1900 (Quad-Core) Memory: Upgraded to 8GB (DDR3) The ALEXON NAS-453-G is an OEM product of QNAP, with hardware specifications equivalent to the QNAP TS-453Pro. The firmware has been rewritten to QNAP's (QTS 5.2.8.3332, 64-bit), so it is recognized as a QNAP TS-453 Pro. OS updates and QNAP app installations are, of course, possible. LAN ports x 4, USB ports x 5, HDMI output, and front LCD display all function without issue. The condition is relatively good, but as it is a used item, please refrain from purchasing if you are looking for a perfect appearance. I have confirmed the operation of RAID5 configuration and SMB file sharing with 4 HDDs installed. I have performed only a simple initial setup with one HDD for verification included. The HDD is currently judged as normal, but please understand that the operation of the HDD itself is not guaranteed. Since it has been initially set up, you can use and reconfigure it immediately from a PC with Qfider installed. Initial settings are: ID: admin5 PW: password5 You can use it as is, but please reconfigure it yourself, including volume expansion and RAID settings. You can use myQNAPcloud (remote access from smartphones, etc. outside the home) by registering. ※ List of items for sale ※ ・Main unit ・1 x 500GB HDD for verification (installed) ・Generic power cable (used) ・16 x 3.5-inch HDD mounting screws (used) (4 installed) ・CD-R (manual, Qfinder, and various software) The HDD mount keys are not included.
