Advice on components

[chudux]

I've started looking into building a LinuxMCE box after finding the website.  I'd like some advice on what I think might work.
Here's the list:
MSI K9NGM3-FIH motherboard

AMD Athlon 64 X2 2.20 GHz 2000 MHz AM2 2 x 512KB Desktop Processor
Kingston KVR800D2N5/1G 1GB 800MHz DDR2 Non-ECC CL5 DIMM kit
ANTEC Fusion Black Home Theater PC Enclosure

2x  SAMSUNG HD501LJ 500GB SATA 7200 RPM 16MB Hard Drive - RAID-1
LITEON LH-20A1S-15 20X SATA DVD Burner (Blue-Ray will come later when it's more affordable)

I currently own 2, Pinnacle PCTV HD Pro Stick's http://www.pinnaclesys.com/PublicSite/us/Products/Consumer+Products/PCTV+Tuners/PCTV+Analog_Digital+PVR/PCTV+HD+Pro+Stick.htm,
and I wonder if these will work.

I appreciate any help or advice anyone is willing to give.

Thanks!
