Ok, so I tweaked the setup a little more today. I removed the foam from behind the grill, I added a 120x25 fan to the bottom to cool my wd black, I also mounted all of my 2.5 spinners behind the mobo. I have my ssd in the tray above my wd black, which you cant see because it is buried behind cables. I didn't have any zip ties, so I just used the straps for now, not a big deal to me. The difference between now and when I assembled it is I do not have to bend the panel to close it, it just slides on nicely. Also my wd black no longer sits at about 45-50c, its back down to the low 30s. All of my spinners are surprisingly cool right now. So now that it is assembled properly, I am pretty content with it. The magnets on the top filter were in rough shape, they need to be reglued, so I just grabbed the one off of my mini c. I was also able to grab her hair dryer and get those badges off while she was out
Unfortunately, because my kid scribbled all over his wall with sharpie last year, I ran out about a third of the way into it, because that's my luck. Overall, I am pretty content with it. My R4 treated me well, and I didn't have a good reason to replace other than I wanted something different.
