resending without html. Lovely that you seem to have to disable html on each reply. I found an $80 rackmount case that has 2 sets of 3x5.25" bays and would take 2 of the 4 into 3 3.5" hot swap bays (icy dock or athena like devices). https://www.newegg.com/black-istarusa-d-416/p/N82E16811165215 Outside of that one I did not see much that had 6 external 5.25" slots and did not cost a huge amount. The above is empty, no fans, no PS. I have an old ThermalKing M9 that has 9-5.25" external bays and I have 3 of the 4 into 3's in it giving me 12 usable hot swap 3.5" drives, but that case appears to no longer be made, and I seem to remember when I bought it I only found maybe 3 cases similar to it and a couple of them were 2x the price. Now it appears that the most important feature of a case is having way too many colorful lighted fans.
