Title says it all. I really want to buy this card http://www.newegg.com/Product/Product.aspx?Item=N82E16814131446 Unfortunately it is around 304mm in total length and my case only gives around 280 or so, not enough for the card. So I know if I buy this card I will have to do some surgery by cutting into part of the HDD cage.
Pictured here:
Now I only need to cut out about 20-30mm deep and about 30mm wide so my question is what is the easiest, quickest, cheapest way to do this. I would prefer to use shears or another similar cutting device over a saw. But I'm obviously open to any suggestions.

What do you need the card for? I wouldn't really bother buying a 5450 now if your looking to play games, more like a 6770 to play everything on medium. You would basically be wasting $30 to upgrade straight away basically.

Does anyone think aviation snips could cut through that? It's zinc-coated steel but it is only a couple millimeters thick at most

Any reason why ya don't but 2 of these which would be cheaper, easier, safer for the PC ? The 6870x2 is just that.

The HD cage structure provides the rigidity for the case, It's the deformed part that serves as the basic structural support and that's what you's be cutting

Heck for another $30 you could buy 2 of these
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and that would give ya 23% more performance than the twin 6870's

If the reason is ya MoBo doesn't support it, ya could almost buy a new MoBo with the saved $100...

I see your point and yes my mobo doesn't support crossfire so I would have to spend at least $125 on a crossfire mobo and $160x2 for the 2 6870s plus shipping to Australia that comes out to be about $474 on amazon, much more than I wanted to spend. Also, the single board 6870x2 requires less power than two boards in crossfire which is nice since I'm only using an Antec 550w which is pushing it for the single board and even more so for two boards. Not to mention my psu only has 2 6-pin connectors.
I will keep looking around but thanks for the heads up on the case surgery. It might have gotten ugly.
