Case is too small, is this a problem?

Hello everyone, I am new here. So please, don't be mad if I don't put this thread in the correct area.

I recently aqcuired a card from a friend. He recently had purchased a newer Graphic card and had given me his old Graphic/Video(unsure which) card. I made absolutely sure the connecters were correct and that my PSU would handle it.

However, there was a slight problem when it was finally here and I was ready to plug it in. I started to insert it in the correct slot, but I found my case was too small! The only way I can think of that wouldn't require me to purchase a whole new case would be for me to cut this small piece of iron that is on the back of my computer. Unfortunately, I'm not sure if it is wise to do so.

Please, can anyone tell me if it is a good idea to do so or should I attempt to purchase a larger case in the future?

If you would like me to take a picture of the case, I can do so. Just ask! c:

A pic of the case, and where it is that you would cut would be great. Moding a case is not uncommon, I would say go for it, pending pics though.

Unfortunately, as you are about to see, the slot is just too close to my case for it to matter whether I have one of those or not. But thank you for the info anyway timbog.

Here are the pictures I promised.

Here is what the situation looks like.

Here is how close the slot is to my case.

And here is how far I can insert the card before the case starts to be a butt and be too small.

Please tell me if I need to take more pictures.

Oh I'm sorry, here, let me try again.

They're in the same order, I think.

I believe it is compatible..

Here is the card type.

Radeon x1600 xt 256MB.

Also, if you can find out, what is the recommended power supply for such a card? Thanks.

Also, there is another problem, the metal bit doesn't have any holes for the monitor inputs.

Well darn, it seems my PSU is lacking anyway. I'm pretty sure 300watts is too low, haha.

I kind of don't understand what you mean by a slot for the monitor. Do you mean someplace else or do you mean the metal bit that covers that hole normally?
