if u want to DIY....first u must survey what cutting tools u want to use ,go to Ace hardware or any hardware shop...find small and good angle grinder or cutter that can cut aluminium...Cost around RM60-120...good brand like bosch or Black&decker are a bit pricey ...
idk any shop in malaysia that can provide service for case mod...but try to go to road signboard maker shop,they usually make and cut aluminium road signboard and hav right tools there...i oso buy my acrilic panel there..
for airbrush...try go to motorcycle or car paint shop ( they make airbrush for skuter ) ,idk the cost to paint+airbrush PC case there but i paint+airbrush my skuter for RM450....it depends on design.. gud luck...
