Thank you for viewing. This is the external enclosure "Rakujo no Shugo Jutaku" (Naked Clan Apartment), capable of housing up to 5 HDDs. I am selling it to organize my equipment. I am looking to sell it outright, so please feel free to negotiate the price. ■ About the product condition and operation • Usage history: Purchased new about 10 years ago and used occasionally for backups. (Currently, I have confirmed that all 5 slots are recognized and working.) • Connection: Used with USB 3.0 • Special notes: As a characteristic of this model, it may occasionally unmount (disconnect) depending on the usage environment (OS and model), but I used it without particularly worrying about it. • Maintenance: I have performed simple cleaning, but I have not cleaned the interior or fans, which would require disassembly. However, since it was only used for backups, there is little dust as far as I can see. I recommend purchasing this for those who can handle technical issues themselves or who can use it for parts. ■ Included items • Main unit only (3 x 2.5-inch mounts are included) ※ Power cable, door lock key, USB cable, etc. are not included. An "AC cord" etc. is required for operation. ■ About shipping As it is precision equipment, it will be carefully packed with bubble wrap and shipped.
