yesterday i decided to use the case i paid a small fortune for, anyways here's the front all cut out and soldered
yes it needed soldering why ? because it rattled something terrible before i did ,yes it looks tatty
but if you look close you can see that the holes weren't straight ,infact all this case was a bit of a mess
here's a pic of the back minus them stupid grid holes smoothed out with a small dremel grinding bit
take note case manufacturers no one wants them in a case, put some proper metal guards in,
they make the air flow so much easier 
anyway now i have that of my chest
here's a pic of the case mod i did (this is a hole i cut last year
)
i used the original hole from my old 425 watt power pack as a template with a dremel type grinding tool to get a nice smooth perfect circle not bad for my first case mod ey
the circuit pictured is from the speed controller which has a little push to make switch on the top to change it's speed, it has a white switch cap that should have been red, but that must have gone up the hoover
top view of case with extra fan switches
(shame the case is so rubbish
)
well it would have been finished today, but for the fact there wasn't enough airflow going through the side hard drive cooler pictured (the fan is on hinges )so i need to do some more drilling
yes there's a bit of gammy tape stuck there which held the fan in as i broke the clip that was originally there
