Old Pentium 4 mobo in new ATX case

[MrDowntempo]

I'm putting togethor a system to throw FreeNAS on using some old hardware I had laying around. Since the machine is going to visible I decided to purchase a nice looking black but cheap case. The mobo I'm using is a socket 423 pin for a Pentium 4. These motherboards require 4 additional standoffs for the Heatsink to screw into. Obvious my newer case does not have the holes for those standoffs. Is there a solution to this problem short of getting a different old PC, or a different new case? Can I purchase a backplate, or a CPU heatsink/fan combo that comes with a backplate?

Thanks!

My only other idea is to just use nuts on the other side. The fan and heatsink I have aren't too big but still I worry.
