Corsair Carbide 400R is a better choice IMO.
^ This.
I bought HAF 912 Combat for 4.4k because Corsair 400R was sold in my place for 5.5k.
HAF 912 Combat comes with 2*120 mm fan, Thumbscrews for Front panel only & no Thumbscrews for PCI, 2.5 cage, and only one Tooless 5.25" inch drive.
So they can't be considered Fully Tool less. Screwdriver is needed to install GPU, remove/attach HDD cage, installing 2.5 inch SSD & removing the back side panel.
If you can find Corsair 400R for less than 5k go grab it.
And don't look into Corsair 300R/200R(flimsy) as HAF 912 Combat(Sturdy) is lot better than both.
Corsair 400R > HAF 912 Combat > 300R/200R
