Ended up coming together nicely. Losing the DVD drive for now. I'm going to have to cut the bay in half to remount it. It's probably been about a couple years since I've used it anyways. I might not bother.

Looks good dude! What kind of fans do you have up front? If I recall, didn't that thing have something like a 360mm fan for intake?
You're going to some lengths to keep that old case going. Is that THREE HDDs in there? I'd offload that to a NAS and tuck it in a closet. I wouldn't be able to deal with that noise from those things.
Thanks, I'm happy with how it turned out.
200mm fan was up front but I had to take it out to set the HDs there. It is three drives but one is an SSD. They don't spin up much. Since I put in a 4TB M2 I could transfer the data and retire them I suppose.
