So all i need for an htpc build is ram, case, hdd and power supply. Then its good to go? Just want to confirm it will stream 1080p/720p from xbmc without any issues? Thanks
Yep. If you have spare parts, great, if not, you can check my post on page 1 for some ram, case, and psu options. If you use OpenELEC, you don't even need an HDD, just a small flash drive.
