I've got a cpu/mobo/ram combo which I took out of my brother's pc to upgrade it. Don't remember mobo model but the cpu is a Sempron single core 2Ghz is a single core sufficient for htpc?, and there is 1GB ram (which I can increase). The mobo's got a pci-e slot in which I can insert the 8600GTS I have. I also have some 400W generic PSU which I can use, and several hdd's lying spare as well... If the above parts are ok for an HTPC, all I'd need to purchase would be a blu ray player and a small neat black case to put everything inside - so while on the topic which HTPC case would you suggest? The smaller the better. Is a single core sempron 2Ghz sufficient? And an 8600GTS 256MB?
