does mobo size matter for a graphics card

[mr.schrecengost93]

will a graphics card rated for atx work on an extended atx mobo?

Most MBs have provision for long GPUs in at least top PCIe slot. Can's remember exactly which ones (MB) have SATA slots in bad place so it interferes with overly long GPUs but even that can be solved by 90 degree SATA connectors.
