need a little help on a new system. i built my first system using an amd 1500+ and and ecs k7s5a. i know some people love the board and others hate it, but i've had no problems with it. i did use an enermax 350w whisper. i'm getting ready to build a new one and i picked up a fry's deal for a 1800+ and ecs k7s5a for $69 the amd is retail so it comes with hsf. the new system is for my in-laws (i like them so it has to work!).

aside from the peripherals, drives and ram, i'm thinking of ordering the following case with power supply as well as a cheaper vid card. they won't be doing any serious gaming, but when i'm visiting, it would be nice to be able to do some light gaming. has anyone built a k7s5a with a cheaper power supply? that's one of the tricky parts of the board.....maybe a bad idea? also, i know tiger direct is kinda sketchy for some people, i personally haven't ordered from them....kinda like ecs....some people have no problems, others can't stand them. any other suggestions would be appreciated. i'm planning on salvaging their old floppy and cd-rom from their old system. any other thoughts appreciated.
