I've got a couple of small compaq deskpro en's that i use for frontends. They are celeron 700's. With the on board i810 they couldnt handle 720x480 video from my pvr-500. I bought a couple of geforce mx4000 pci cards for them and now they work like champs. I highly reccomend this solution. The pci geforce cards can be had for less than $50 new. A lot of them have svideo out as an added bonus.
