I'm fairly new to the htpc build and have been researching daily since finishing exams a couple of weeks ago.
This is what I have come up with so far and feel like I am very close to pulling the trigger and ordering the components.Motherboard
: Asus P7H55-M Pro Micro ATX Intel $95 link
or ASRock H55M/USB3 R2.0 Micro ATX Intel $87 linkProcessor
: Intel Core i3-550 $115
(basically same price as 540 and 530 model) linkMemory
: G. Skill F3-12800CL9D-4GBRL $55 linkHard drive
: Western Digital Caviar Black 1Tb $87 linkCase
: nMediaPC HTPC 5000B $60 linkPower Supply
: Corsair CMPSU-430CX $34 linkTuner
: Hauppauge WinTV HVR-1250 $40
(mainly for hd channels through antenna) linkKeyboard/Mouse
: Logitech MK320 $33 link
Using Windows 7 64 bit
That's it for now. I will be using this mainly for watching media files, netflix, recording and pausing hd local channels, quick and easy access for all ripped dvds and music, eventual blue-ray add on, and that's about it (not going to be used for gaming). I'll have it hooked up to an hd capable tv through the hdmi out.
From my research it seems that all these pieces are compatible with each other. Any suggestions for alternative parts would be much appreciated.
