Hello,

Has anyone used one of these SAS backplanes/chassis in their custom builds? Seems like a nice organizational feature for very cheap < 15$.

643705-001 HP SAS Hard Drive Backplan with SAS Ribbon Cable 660706-001 | eBay

Might model up a 2x5.25" bay to 8x 2.5" drive chassis to use this backplane with.

If anyone has used them do you know if the power connector is compatible with standard 6pin atx power supply? (or have a drawing/pinout)

Thanks,
-Arthur

Ended up going with the intel8bay linked above as it is 12gbps.
Designed a ducted enclosure for them. the backplane is too wide to fit in the 5.25" drive bay without chopping off a bit more than I would like to of the case.




However have not been able to format the gd SAS hgst drives successfully.
