HighPoint RocketRAID 2722 8-Port External SAS Question

I have one of these on the way.  Long story that I'll explain in a RESET Podcast.  http://amzn.to/2GJRX5d

I've never done the SAS cards but my question for you is:

 

Have you ever seen this external SAS port turned back into the inside of the case?  Like with a cable as such?  https://www.ebay.com/itm/Mini-10Gbps-SAS-SFF-8087-36Pin-to-4-SATA-7Pin-HDD-HDD-Splitter-Cable-1M-Reverse/162727863911?epid=1518256476&hash=item25e3562667:g:QQ8AAOSwZPZZ85xM

My other thought was to put a box beside it and simply power drives with a power supply and nothing else.  Length becomes an issue. 

There are always other options. Cages. One with a fan too.

Burst mining expansion?

 

My microserver has a cable from the Esata port running back inside to connect additional drives.

These cards are usually available in both internal and external connection variants. They have either SAS SFF-8088  or a SAS SFF-8087 connector on the card. A mini SAS 4X SFF-8087 to Mini SAS SFF-8644 1 metre cord is available to solve the problem to convert.  In my case I have one connector connected to drives inside the case (4 of them) and the other connector connected to an external 4 bay JBOD as there was no more room inside the case for more disks. Note also these cards can come with or without RAID controllers.  In short when buying these cards make sure you know which connector and which controller you are getting.

EDIT: Note on temperatures. I have 7 drives inside the server case ( 4 off the MB and 3 off the LSI card) and 2 in JBOD (room for 2 more) which is a TowerRaid TR4X6G.  I had to add an extra fan onto the front of my case to get disk temps down to 30-32.  The TR4X6G has its own PS with a small fan and an 80mm fan at the back blowing through the disk case to the front. With 2 disks in the JBOD temps went to 58c which was unacceptable.  So I removed the front door and put a 140mm fan on the front blowing in and reversed the 80mm one on the back.  This reduced temps to 40c which was only OK.  So I replaced the 140mm fan with a Noctua Industrial running at 3000rpm.  Temps dropped to 30c for the 2 fans in the JBOD. Only problem is my other complains about the noise when she enters the room but my drives are happy.

Thank you both. Long story short, it's on the way and I didn't pay for it. Was thinking of trying to make the most of it without investing heavily.
