Recent years computer all comes with PCIE so chances are, its the casing
I know cause I have a god damn small casing. Mind you these days, casing are so short, even though it meets the medium size ATX spec, that's just the height. 4 CD bay, 2 floppy, 5 hard disk, yeah.. but the length of the case is pathetic.
Unfortunately, no, you cannot fit the card in without changing the casing. 4650 is indeed a long card. You can't cut the card or so. I wouldn't say cutting out the hard disk bay to be a good idea too, lol.
I changed my casing to ensure it can fit a 9800GTX+. Its the best option.
Bumping an old post because I'm in a similar situation.
I also have a Dell E510 and I'm looking to buy the same HIS HD 4670 IceQ Turbo card. Were you able to fit the card? This looks like the best 4670 for the money so I'd really like to get it. If it won't fit, does anyone have any suggestions that will?
My E510 is not a slim version and I haven't made any changes/upgrades to it yet. Thanks.
