I may need up to 4 3.5" bays for a RAID array... or may have to get an external enclosure. Was trying to think of an elegant way to get a drive cage in there with a fan blowing across the drives and out the back. Also... seems almost a waste to not show off the reservoirs since they're usually a highlight of any watercooling build. Perhaps a window on the hidden side but only the top half since the area in front of the PSU where the cables connect is just a big old mess no matter what... was thinking perhaps a cable shroud similar to the Coolermaster HAF:
Just some stuff I've been mulling over myself.
