I modded my standard Packard Bell to make it look better. I added 4 green ccfl's in it with a regulator to make them go slowly on and off ( like a glowing radiation effect ) putt some red lights between the Ram modules, put some red led ram mod on the ram strips going up and down on the strips, changed the small fan on the back for one with green leds and got a thermaltake SpinQ VT cpu cooler with a red led in it in.
Because my PB ipower x3.0 only had a very small opening on the side you couldn't see all of this. ( and also not my gpu which i love to see, specially the copper heat pipes )
So i took my grinder ( didn't have any other, better tool ) to make a big hole in my cover, so you can see all. ( 20x20cm )
Because with a power tool like a grinder you can't cut it in a nice straight line and it looked really bad. I knew that would happen so i bought a metal strip and a spray can of black paint. Also i bought a mesh panel ( most expensive part ).
Glued the metal strips over the side of the new hole, glued the mesh panel behind the strips, sprayed everything black and it looks pretty decent i think.
With the sun directly shining on it you can tell it's home made but that doesn't happen here, with normal lighting you can't see i did it myself.
This all was scary as hell though, putting a grinder in a perfectly good cover, hoping you are right and hoping it will work out in the end.
