Tool case PC mod

so i think i found a case for a pc inside a suitcase build, im gonna need some tools to do some cutting and im gonna need the backplate of a normal pc case where you mount the motherboard and what not but i think it can work. i did the measurements and the parts should fit, heres the case

what do you guys think about this?

edit-does anybody know of an extremely cheap itx pc case with great cable management where i can get the plate to mount the motherboard. the motherboard will be full atx since i have enough room in the case but will i be able to mount the motherboard on the plate even if its from an itx case.

could really use some feedback.
