[mythtv-users] New system configuration question

[Harry Orenstein]

I just got a ThinkCentre M90z all-in-one desktop and I'm trying to figure out 
how I could use it as a combination frontend / backend for Myth.  I was hoping 
I could get some feedback / suggestions.  It has an i5-650 processor and Intel 
GMA HD graphics.  There are no slots for expansion other than a mini PCI 
express slot that I believe is currently used by the wi-fi card (though I'm 
willing to remove it).  Options I can think of are:

1. USB connected HD tuner (e.g.: DVICO Fusion USB, HVR-950Q)
2. Ethernet connected HD tuner (e.g.: HD Homerun)
3. Crystal HD to accelerate video
4. MCE USB remote

Anyone have any experience with limited configurable systems?  Can the built-in 
graphics handle HD video in Linux (now or soon)?  I'd appreciate any 
suggestions anyone has for any options that I've missed or specific tuner, 
remote and video hardware.

For a bonus question: anyone using a touch-screen for input in Myth?  Not that 
I really want to walk up to the screen every time I want to navigate a menu, 
but since the PC already has it I was wondering if the joystick option in Myth 
can be used for touch-screen input as well.

TIA!
