I wanted to post my HTPC hardware, along with my current recommendation for a new Windows 7 HTPC build. I know there are many cheaper HTPC options today (Raspberry Pi, Ouya, etc...), but in my experience nothing beats a Windows 7 HTPC. Definitely also check out the forums at xbmc.org for other build recommendations. Below is simply what I use, and my current recommendation for a very nice budget system.
My current HTPC:
Case: $60
SilverStone ML03BCPU: $127
A10-5700 APUCPU Cooler: $38
Cooler Master M4Motherboard: $75
ASRock FM2A75 (Newer Version Available now:
FM2A75M)
PSU: $25 (Currently on sale)
Corsair CX430RAM: $37 when I purchased.
Kingston 8GBSSD: $185 when I purchased.
Samsung 830 256GBCase Fans: $14 x2
Noctua NF-R8 x2Total: $575
Mine is way overkill, and a new HTPC doesn't need to cost. I wanted mine to be powerful enough to play current gen games, and it is at medium graphics at 720p.
Here is my recommended whisper quiet build today (December 2013) that is more than adequate for 1080p playback, and some light gaming.
Case: $60
SilverStone ML03BCPU: $55
A4-5300CPU Cooler: $38
Cooler Master M4Motherboard: $50
MSI FM2-A55M-E33. Really any Micro ATX FM2 motherboard with HDMI will work perfectly.
PSU: $25 (Currently on sale)
Corsair CX430RAM: ~$40. 8GB (2 x 4GB) of whatever. There are always deals.
SSD: ~$90 - It's easy to find one on sale. ~120GB is more than enough.
Case Fans: $8 x2
ARCTIC F8 PWM x2
Total: $374
