Questions about this item

How loud and hot does the chassis get when all 24 bays and three 12038 fans run continuously?

Two 12038B ball-bearing fans are fitted as standard and the backplane includes temperature control; the third 12 cm position is available for extra airflow if needed.

Which host interface and cables are required to connect the 12Gb/s expander backplane to my RAID card or HBA?

The backplane uses Mini-SAS HD (SFF-8643) connectors, so you need matching SFF-8643 cables and a controller that supports 12 Gb/s SAS.

Will my existing ATX power supply and standard 12"×13" motherboard fit without modification?

The chassis accepts standard ATX supplies from 800 W to 1500 W and motherboards up to 12"×13", plus seven full-height PCIe slots for add-in cards.
