Typical onboard sound. It's fine for anything I'd want computer audio for.

Video: There is no onboard video, and the 400SC ships with an ATI ISA card. Remember that the SC designation means that it's intended for server use, so high-end video isn't going to ship with the system from the factory.

However, once the AGP is turned on in the BIOS you'll find that it's really quite speedy. The high-end ATI cards seem to work just fine; however, some Matrox cards have caused problems.

Do you need expensive video? I'm still doing fine with an ATI Radeon 9200 (not SE or anything else...just plain ol'e 9200). Stay away from any Radeon that says "SE"...there's a reason they're cheap.
