I have a Pundit P1-AH1 (socket 939) and I'm quite happy with it.
I capture HD content with the OnAir GT USB capture device and the processor cruises at around 35% during recording of 720p or 1080i content. The system fan is almost silent because of the low CPU load and I put a very quiet 250GB STA HD in it. You can't hear the computer from more than a couple of feet away. I use a Logitech wireless keyboard and mouse and even have a Nexus-S satellite card in it.
Setup was a bit tricky- to get the S3 & S4 power modes working correctly and I made the mistake of using the included Nvidia SATA drivers for the hard drive which pegged CPU usage at 95% after resume from sleep mode, but I did some internet research which recommended rolling back to the default Microsoft WIN XP SATA drivers which cured the high CPU usage after resume from sleep problem.
The only minor things I don't really like on the P1-AH1:
1) Only 2 USB ports on the rear of the case- the other two are on the front which means you have to have the front panel opened to use the third/fourth USB port. Workaround for this is to buy a USB backplane from Amazon (http://www.amazon.com/exec/obidos/AS...6-20/ref=nosim
) or your local computer builder and connect it to the extra USB port header on the MB, this way all your USB connections are still in the rear.
2) The only firewire port on the computer is on the front panel too- like the #3 & #4 USB ports mentioned above.
3) It seems that the P1-AH1 is designed to pretty much stand up vertically on edge, no factory options to lay it down flat for use in a entertainment system stand like your regular audio/video components- DVD player, amp, etc... Workaround: Remove the Factory base mount and buy 4 rubber 1/2" self stick pads at local hardware store- put them on the bottom of the case. Now you can use the P1-AH1 mounted horizontally.
All in all, I'm very satisfied with the P1-AH1. No stuttering issues with HD content playback. System is rock solid stable, after working out the initial installation bugs- I never miss a scheduled recording now, and my system spend 99.9% of it's day in S4 hibernation mode (1 Watt power consumption
). With it's small size, wireless KB & mouse and being black... everyone thinks it's just another AV component on my HT shelf- nobody has guessed it's a computer yet
