I would look at using an adaptor:

i did look at using a adaptor but it whould mean cutting section out the back of the case.
also id rather cut a £20 gfx card if it can be done than have to mod a custom built case that cost £200
You're sod out of luck if you need it in a low profile case though. Unless you can use a flexible adapter and have a PCI lot in the case without a motherboard slot behind it.
You can also get motherboards with open pci-e slots or carefully cut the back out of the slot.
Works with any pci-e not just x1 although you may well criple the bandwidth the card needs, but for a low end card that shouldn't be an issue.
Just don't do the classic one of cutting a pci-e card to fit into an AGP slot.
Must admit I was shocked when I first found out you could cut down a card/cut open a slot.
I've done the x16 to x1 slot cut mod succesfully to a £20 ATI Radeon HD 2350, it wasn't difficult and only took a few minutes with a dremel.

so if you cut a x16 slot to a x8 slot or x4 slot whould that give more bandwidth or even work.? as i have never seen anything other than a x1 or x16 slot gfx card.Quote:

Cutting a x16 card to x8 or x4 would work, cutting a card from x16 to 8x effectively halves the bandwidth, cutting it down to x4 takes bandwidth down to a quarter and x1 to a sixteenth. Reducing the bandwidth also reduces performance, however many cards don't fully utilise the full bandwidth of a x16 PCI-E slot and reducing the bandwidth to a certain degree shouldn't have a noticeable impact on performance.Quote:

In my example, the HD2350 is not a fast card, it would struggle to saturate a x1 PCI-E lane and modding it from x16 to x1 will not have an impact on its performance at all.
I'm with Pob on this one. Why go through the bother of chopping the graphics card when you can more easily open the PCI-Ex slot. OK, you void your Mobo warranty but it's an easier mod.
You do quite often get components in line of the back of the slot though, preventing you from actually installing a longer card. I would rather mess up a £20 graphics card than a £50+ motherboard.Quote:

Fair enough. Must admit I'd not thought of that!Quote:

As funkstar says though, there's so much room behind an x1 slot that they often got components tagged in behind them, so in that case it's probably going to be the card that gets chopped ;)Quote:
