[question] Do You Know Where I Can Get This?

Is there any store that I could possibly get this power supplier from or one similar to it if you know of any?

looks like a proprietary one. you probably need to get it from gateway directly.

Nope never seen one like that being sold. THats what you get for buying a gateway

You might be able to squeeze in a microATX power supply in the slot.

just call up gateway and give them that part number, 6500648
