totally depends on your disk...i'm a comp newb but do a lot of work around the house, have some grinding wheels I've used to go through rebar and other steel atleast an inch thick...just need to spend more $$$ on better wheels and tools.
Case looks good, still haven't finished my mods...i did the inside of my 900 white instead of black...with blue wrap on the wires. will see how it looks once I get it all back together.
