Also Z400 does not match standard ATX mounting holes 100%, so you might need some slight modding for 2-3 non-standard mounting holes in your case.
HP seems to like doing the mounting hole thing.
At some point I was gifted a very small HP PC which came in a tiny (and for my tastes too noisy) ATX-alike case. I wanted to transplant it to a new case (a 'new' case made by Antec which at least had better cooling options than the old case) when I found out the mounting holes didn't match up. Of the 4 holes, only one had the correct spot with the other 3 being in different spots. I still managed to botch the HP motherboard into the Antec case by using some of that electrical isolation tape for the 3 not matching standoffs, a piece of plastic stuck in the top of the case using double sided sticky tape to press the board against the tray and a block of glued plywood sawed to the millimeter on which the motherboard rests.
I'm actually typing this message from that system 🤣.
The PSU seemed to have the correct color coding for standard ATX and the (scarce) info I found online did indicate it was standard ATX, but I didn't want to take any unnecessary risks so I kept the old PSU in and moved it to the Antec case as well.
The main reason I kept this system is because I didn't have any money for anything better (the PC that was supposed to replace my Phenom II had also died and no money etc) and the i7 7700 that is in it was good enough for me anyway.
This board doesn't even seem to use a standard sized CPU mounting system or at least the CPU HSF I had wanted to use to replace the stock noisy one didn't seem to be able to fit.
