Those cuts really need some serious work but providing your going to make them perfect then thats fair enough.
As above, youve cut out the vents, all the little holes thats to the top and bottom of the console, youve cut them all out.
Also, i don't know if youve took this into consideration either, how exactlly are you going to fasten it all together properlly? the top screws to the shielding and mobo etc from underneath, then the bottom of the cash is put on and all clips together. Being as you have cut the mountings from the top panel, how do you intend fastening it together properlly so it doesn't fall apart easily?
