Hi Guys I'm about to re-build my athlon HTPC using new components and move it into the same room rather than next door. I've decided that intel components run a lot cooler hence quieter. My question is around CPU spec that I need. SHould I go for the P4 2.6 with HT or is this too much power? would I be better off with a cereron 2.0ghz? Would this do the job? Or would I be better off with the P4 but UNDERCLOCKING it? I'm thinking of either the Zalman copper flower cooler or the Thermalright SK-900U just for the sheer size of cooler. I would prefer to cool the CPU passively - just using one papst case fan to shift air through the case if necessary. Let's ignore the PSU fan for the time being because it's going to be the 200W PSU included in the DIGN HV5 HTPC case and I don't know how quiet it will be. Has anyone tried running a P4 fanless? Does anyone run a celeron fanless? Will a celeron be enough? Will the 200W PSU be enough???? oh - and if anyone knows of an especially quiet DVD-writer then that would be cool as well... Intended config: CPU + motherboard Seagate Barracuda V 120GB Nebula Digi-TV PCI card EIDE DVD writer Radeon 9000 pro fanless 512MB RAM. Thanks John ---My current system-- My current HTPC runs; Theatertek DVD player Nebula Digi-TV card - used as personal video recorder and tuner. musicmatch MP3 player Girder ATI remote wonder and I'm thinking of using two digi-TV cards to give me true record-one-channel whilst watching another channel capability. My current HTPC uses an Athlon XP1800+ and is fine.
