I don't expect particularly snappy performance from ITX motherboards, but I don't expect them to be as slow and unstable as that one.
I have a board with an Atom D 330 and nVidia ION onboard that I absolutely love despite it's lack of any expansion. It makes up for that somewhat by having like eight USB ports on the back and headers for more, as it's not a performance system expansion through USB 2.0 is fine and there isn't any real need for PCI-E, it has also always worked when I've had nothing else to get things done with. Surprising really, given that it's another Asus board and I've never really seen what the big deal was with them, silly colors and cheap Chinese PCBs that have all the integrity of a damp egg carton, this is obviously the odd one out.
I only bought it because I needed a new server and it was on offer due to being a display model along with the case it lives in, the store tried to charge me full price for the case but I told them to get lost, built the whole thing for less than £100 around 6-7 years ago, was a steal really.
As for the pavilion, it was donated by a friend after his idiot pal ruined it and stripped out anything useful as well as trashing my brand new WD Blue... He was meant to be 'fixing it up for me' despite me saying I would just do it myself and to send it with the knackered fans and blank drive. Neither of them wanted it back after I found the system was useless, nor could they care less that they cost me a hard drive so I don't talk to him anymore because he's insisted for years I know nothing about computers but his buddy who wrecks every hard drive he can get his hands on does.
