looking for a 3 1/2 in server case for adding 5 Sata drives

You don't need an empty computer case... hard drive cages are sold separately. I've seen these enclosures support 5 - 7 hard drives.

Here is one... probably not what you need, but if you do a search on "Hard drive tower"... you might find exactly what you're looking for:

I did find a server case that gives support for 5 hard drives that use 5/14 mobile racks but now I have one drive that the Sata multiplexer says it detects but Windows is finicky about recognizing it as there At times and find that annoying.Checked it a normal external case and it always gets recognized by windows so know the drive can be read and writen to but under the multiplexer unit it keeps having problems from Windows even seeing it.the reason for using the multiplexer and the server is to reduce the excess clutter of another power supply and cable and another case/How can this problem be resolved using the multiplexer rather than an external case Only one drive has this peculiarity regardless of what racks it's secured in but know that it does work
