first sorry for my poor english, Im from Argentina Ill give you some tips on best hardware for htpc... VGA Always look for vga cards that already come with aftermarket coolers for 10dls or 15dls more... never buy a card with reference coolers because they are noisy and dont dissipate heat well enough... high end -Sapphire 5850 Vapor X -mainstream Sapphire 5770 Vapor X / nvidia gtx260 -low end Sapphire 5670 / nvidia gts 240 almost all ATI 5xxx series have Hdmi output, and consume less power than the nvidia counterparts PSU Coolermaster Silent Pro or any Power & Cooling, not too expensive and silent enough CPU and MOBO -high end Intel i7 ... dont buy this overpriced piece of s*** -mainstream Intel i3 or i5 (INTEL) with an H55 mobo AMD Phenom II X4 with 785g, 790gx or 890gx mobo (this mobos have a nice integrated video that is fast enough for light gaming and 1080p video acceleration) -low end Intel e5400 (socket 775) with p45 mobo AMD Athlon II x4 with 785g mobo some good motherboard brands: asus, gigabyte, msi, etc Look closely to the heatsink on the northbridge because they tend to get very hot and can be a pain when using a case with poor ventilation, so aim for those with big heatsinks with heatpipes on the northbridge and mosfets There are dozens of good and silent aftermarket coolers for the cpu. Coolermaster, Thermalright, Thermaltake or Scythe, to name a few good brands. If you plan to buy a small case, you can forget about ATX size mobos and aim for mATX mobos... and take measures of the big vga cards like 5850 or gtx260 and some aftermarket coolers are 12cm height so they cant fit in small cases. My current htpc hardware is Case: Coolermaster Elite 360 CPU: Athlon II x4 620 Motherboard: Gigabyte 785g Memory: 2gb DDR3 1600 VGA: Sapphire 5670 with accelero cooler LCD LG 32 1080p I can play games like Street Fighter 4 and Mass Effect in medium to high settings, all emulators from mame to pcsx2 and dolphin, 1080p videos and so much more again sorry for my poor english
