Ya, I have the 475. It only has something like 500K memory, which sucks. The link I posted has some benchmark tests and by upgrading the memory to 2 gig, the improvements are significant. Upgrading the CPU doesn’t yield much at all, but they are cheap, so I’ll most likely do that as well. I found the link and memory on the HP forum you posted the link to. I agree, the guys there are very helpful.

For less than $150, I can upgrade the memory, cpu and add a 1.5 T hard drive, which will give me 2.5 gigs.

I didn’t look at the Popcorn Hour, but I do have a Slim Devices Duet and absolutely love it. I use my server for nothing but music via the Duet. It’s so cool; three friends of mine are going to do the same thing.
