Hi Everyone. I've read through the thread and I think I understand at least most of it. I have been running an Unraid server for about 5 years now. But it has just worked and been trouble free. The most advanced thing I have done is to run Plex in Docker. I use it mostly as a media server and a file server for the family. Giving everyone a safer place to store their files. Right now this runs on a 10 year old HP Envy computer that has an AMD A10 7700 that has 10 core. I want to move the server to a Lenovo with a much newer i7. But the case is too small so I was hoping for an external case for at least 4 hard drives. I'm looking at the solution listed below on Amazon. It is a four bay box that comes with a QXP-400eS-400-A1164 controller card. Am I correct in thinking that this will work without issue? There is also an 8 bay box that comes with a QXP-800eS-A1164. Does the 800 in the part number mean that is can natively handle 8 drives or is that board a multiplier? Thank you to anyone who knows more about this than I do and is willing to help. The link may be to the 800. You might have to click on the 4 bay in the description. https://www.amazon.com/QNAP-TL-D800S-Enclosure-Interface-QXP-800eS-A1164/dp/B086WCRGXV/ref=sr_1_3?crid=UXI727J80ALC&dib=eyJ2IjoiMSJ9.enor6rm6F3bLFWDOlnofEemvMifI9UT8DpFUn32jK7Q.oAwF8KTAh3zjUpKAiaS5-4-G0gsM_gDhd0hUk704nOg&dib_tag=se&keywords=tl-d800s&qid=1749679363&sprefix=tl-d800%2Caps%2C149&sr=8-3&th=1
