any system parts you want, i'm running an intel celeron 1.8 ghz w/ 2gigs ram and as many sata drives as i want since i bought the license for up to 6 (8) drives (i don't remember which one it is).
as for a guide...
buy a motherboard (anything you want)...
i am no guru.. but i have one in my condo.. mounted from the ceiling...
mine is not 720p or 1080p for that matter... it outputs 800x600 and xbox live and tv looked half decent on it. it is however a 3-lcd projector and i love it.
i've got an older 350 watt psu that i used in my desktop from a few years ago. pretty sure it still works. its got a p4 power connector on it... can't say much more then that. i'm pulling it out of an old case and replacing it with a new one for a new machine build...
hm... says it can do...
i got an htpc which could be used just as a desktop...
Asus - Pundit-R - $125 - shipped
- P4 2.4 ghz
- 1GB PC3200 RAM
- IDE HDD (Computer supports SATA, includes cable) - haven't decided what HDD to throw in here yet.. but could work something out.
- 52x32x52 CDRW
- ATI Integrated...
funny that you're looking for one.. i have one going back for repair sitting on my dinning room table.. nice amp though.. distribution centers won't have them instock as they're yester-generation.
