First off if ur case it a SunBeam Transformer Then thats the same one im getting
(in one or 2 days)
For a motherboard id go for the M2N32-SLI Deluxe or the Wireless edition if u want full 16x 16x SLI speed thats sitting in its box right next to me
And as for the PSU Dont get or use the PSUs that come with the case
Its better to get a individual one.
Right now im hopeing that i dont have to take the top fan on the Transformer case cus the PSU if to big (Lets all hope)
