Product/Model Name: QNAP / TS-673 CPU: AMD RX-421ND 2.1 GHz (4 cores) Memory: Upgraded to 16GB (DDR4) LAN: 10Gbps Dual Port NIC installed (Intel X540-AT2 controller) Firmware has been updated to the latest version (QTS 5.2.7.3297). All LAN ports x 4 (+ 10Gbps ports x 2) and USB ports x 4 are functioning without issues. The unit has been wiped with alcohol to some extent, but some of the plastic fasteners on the bottom are damaged (see photos). Other than that, it is generally in good condition, but this is subjective. Please refrain from purchasing if you are looking for a perfect appearance. RAID 6 configuration and file sharing via SMB have been verified with six HDDs installed for testing. A 500GB HDD for testing is included and has been set up with basic initial settings. The HDD is currently showing a normal status, but it is for testing purposes only, and the operation of the HDD itself is not guaranteed. Please understand this. Since it has been initialized, 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., when away from home) by registering. ※Included Items※ ・Main unit ・1 x 500GB HDD for testing (installed) ※ No screws are included as the trays allow HDD installation without screws. ・10Gbps Dual Port NIC (installed) ・Generic power cable (used) ・CD-R (manual, Qfinder, and various software) While there is a possibility of a price reduction at my discretion, I generally do not accept price negotiations. Immediate purchase is OK, but: ・400 yen off without the HDD ・1,500 yen off for downgrading memory from 16GB to 8GB ・3,000 yen off without the 10Gbps NIC is possible, so please contact me with a comment before purchasing if you wish to do so. If there is a malfunction after arrival, returns are accepted within 3 days of arrival.
