Ok so I currently have a Dell Studio XPS 7100 and want to upgrade the PSU to a larger 850W source. My problem is that the current case is too small to fit one. Is it possible to transplant all the parts from the current case to a new larger one. I am mostly worried about the motherboard as I have heard they don't fit in custom cases, but any help would be appreciated. I can supply any other info you may need.
Dell is known for having non-standard mounting systems, and you will have to ensure that the motherboard stand-offs match the pattern in your new case. If not, you may have to drill and tap a few holes; not too difficult to do.
If you add fans, 'daisy-chain' connect them directly to the PSU using Molex connectors.
