I have a similar setup with the same case haha recently built as well. Your use-case will be more than fine. My only suggestion, aside from try and get more RAM. If those hard-drives are in a redundant raid setup, and you don’t already have one, get a backup drive too. Especially if the price for the drive IA decent. Last thing you want to do is to buy a replacement drive later when prices are jacked up or have to do the RMA process with only 3 drives running your data.
