I am buidling my own case out of sheet metal and well I am not the best with cutting to the mm so I have rough edges. Basically I have a box everything but a top(desktop style case) and rough edges on each edge. Now what do you guys think is the best way to make them smooth. Bondo was my first thaught just slather it on the edges and smooth it down. That is the only way I can think of?
 
I used a dremel to cut it. I am saying the creases where the edges connect would it look better to use a corner brace type thing running all the way along the edges or to bondo them and make em smooth? This is a HTPC so I want it to look nice.
 
covering edges with bondo like that might work, but the bondo could crack from moving the case around, bondo is made to fill dents and dimples not holes or voids. One way you can cut sheetmetal is to score it with the backside of knife blade (turn the knife so the blade points up and use the back of the knife point). Score it several times and bend the metal over the edge of a table. then use a dremel/cutoff disk to finish the cut. this gives you a groove to cut in so the dremel does not slip and yields very smooth cuts.
 
I'd use an air die grinder with a scotchbright pad........I actually use 'em to cut down welds in aluminum. If you have an air compressor.....die grinders can be bought cheap from places like Harbor Freight.......plus the 3 inch cutoff wheels are infinitely more durable than the dremmel ones.

Get yourself a bastard file set from your local hardware store and give 'er a lil elbow grease. You'd be amazed at what you can do with five hours and a bastard. :D
