Keep in mind that the issue of weight and space is the "FULL ATX CASE" more than the motherboard itself. The performance of a non-PC name brand mobo is on par with full size ATX boards, usually. So perhaps just put whatever board into a small light-weght case for gaming? Also, a MicroATX mobo can handle a full size 8800 video card and if needed an audio card.

You can transfer your PC into something lighter... Also, there are some ultra-light cases that will cost quite a bit more money. This case weighs 18lbs with PSU. Add about 4-5 lbs for HD, DVD and video card, etc. It includes an Active PFC PSU at 380watts that should handle a single GF7900 card.
The LianLi cases tend to be among the lightest cases as well: http://www.newegg.com/Product/Produ...5&Subcategory=7&description=&Ntk=&srchInDesc=
Note: bigger PSU tend to be heavier... etc.
