I've been looking at building an HTPC. I know the Mac mini will do that quite well, I'd rather have a go at building something and trying Ubuntu. I don't have much HD content yet, but I will in the future. The Atom barebones systems look pretty good for the HTPC environment. Do you think it can handle Blu-Ray? If the Atom isn't the right thing, do you think I should go with Intel or AMD? As a yardstick, I can get a Phenom X4 for around the same price as a C2D. If a barebones doesn't work, where can I get a good quality, pretty good quality HTPC case with 5.25'' and 3.5'' bays? The ones at Newegg are either cheap and shabby or expensive. Another necessity is a WiFi card, preferably 802.11n. Are there any that work with Ubuntu? I'd like to stay at $400 or less. Thanks for your help.
