my BE in our study, so is focused on low noise. used to be in the loft but the HDD's vibrated the chassis so it echoed through the joists and made it noisier than it should of been.
the hardware is a CFI A7879 case, and as i mention before: Pentium G3240, reasonably early model 4tb WD Red, and the quietest 2.5" drive i had spare. SSD boot drive.
stock intel CPU cooler, stock PSU. I've replaced the standard 120mm fan and fitted a quiet noctua version which was the main noise culprit. while the drives are quiet, they are the most obvious noise coming from it. I've got to the point where i'm chasing my tail with it and would require SSD's to make it practically inaudible.

so yeah, the biggest issue is finding the right drives at the right price. anything i've bought new has always been quieter than previous generation disks. however one of the biggest noise killers is anti-vibration HDD trays. ime the majority of HDD noise can be attributed to vibration throughout the PC case. much like running a HDD on a wooden desk, vs running it on some foam. foam vastly reduces the noise levels. you'll still get the head churning noises.
i'd take a look at the DB levels of in-budget drives. WD blue or greens (do they still make?) are probably the quietest, then red, then blacks. i'd have no problem running WD blues outside of RAID and thats purely down to the HDD firmware being tweaked for RAID usage so should work more reliably.
