@Chrispy_: yeah, it's a 160mm PSU. I think it should fit with my ~180mm burner based on
this photograph and warning. Plus, the PSU is totally modular so I'll only have a few cords plugged into it. Since you mentioned the cooler issue, I might just purchase Xigmatech's Loki (smaller 92mm version of the Gaia) and keep it if I don't need to use it. The friend has a NAS box I set up, but I may go ahead and pop in one of the Samsung HDD's I have just for bulk local stuff. I'm alright with metalworking — I plan on tinkering with the case to eliminate whatever rattles or vibration there might be, anyway — so it's not out of the question that I'll chop up the drive cage if it annoys me!
Thanks for the advice.
@DPete27: probably not, but it's a $15 difference. Also, I just prefer Mushkin because they're an American company whose service is fantastic in my experience. I like supporting them!
