With the lack of a reliable HD STB, this price point should be acceptable.
How you say?
There will of course be some comprimises.
I have used pricing from one supplier to make it easy in case one needs to purchase.

Others that may be ok.

From experience the psu is good quality and quite.
Is the 8200 enough GPU for the job?
Last test say no.

But that was 6 mths ago, maybe drivers have improved.
I might borrow one to try when time permitts.
Will the cheap usb tuner work? Is it sensitive enough?
It should do from reading about other cheap tuners.
As for sensivity, don't expect too muh for the price.

Once windows is install ontot he flash drive, you would use a write filter system to extend it's life and speed up the system.
Best case sceneairo for this box? XP/Media portal combo
-Recieves Freeview DVB-T HD and displays with no stutter
-Displays EIT EPG, Now/Next (maybe full day). If internet connection available then full epg via XML.
-Low noise as is.
-Expandable as user's budget permitts. PVR is already supported, just add more storage.
-HD via Component, with suitable DVI cable
-More flexible than and STB, play sll those crazy youtube videos you downloaded.
Cons
-No MHEG5 EPG
-More power required than a STB
-No antenna passthrough
Potential problems, unknowns.
-Is the 8200 enough? Price does not matter but we may loose some features with a discrete video card.
-Will the cheap tuner work?
-How limited is the remote? Standard MCE or it's own program only.
-How long will it run for without a reboot?
My parents are looking at a new TV so might get a chance to try this build out for them.
