In Figure 1, you have an overall look at ASRock N68C-S UCC. Since it is a low-end product, it uses the microATX form factor.
The GeForce 7025 offers one PCI Express x16 lane and three PCI Express x1 lanes, and this motherboard provides one PCI Express x16 slot, one PCI Express x1 slot, and two standard PCI slots. Keep in mind that all these slots are PCI Express 1.0 and not PCI Express 2.0, so they provide half of the bandwidth of competing products based on chipsets that support PCI Express 2.0. In other words, the PCI Express x16 slot available on this motherboard is equivalent of a PCI Express 2.0 x8 slot. But at least you will be able to disable the on-board video and install a “real” video card if you want to.
