I came across an AV (nø HighDef) DirecTV DVR, so naturally I scrapped the shit heap. I got some goodies; initially looking for the HDD, which is a 160GB (IDE Ultra/PATA!) Seagate ST3160215ACE. As well as the fan: a 50mm, 12V 0.7W, two-wire, maglev bearing by Sunon. They also have nice 50mm fan grates that are easily removed with any metal cutting saw, once you peel away the surrounding labels. I prefer Zippo fuel or straight petrol to clean off any label adhesive on any project, although light petroleum distillate like Zippo often proves a better choice then raw stuff. My favorite use for the grates are in PSU's like a slim or elite 360's PSU. Although you want a fan with about double the wattage of 0.7W for a 360 PSU.
I then saw the PSU has a mess of little capacitors that are about the size of an Xbox clock cap, but their specs are way higher. Stock clocker is 2.5V 1µF if I remember, but one of these monsters is 50V 10µF, and the bigger ones are 25V 100µF. The biggest that will physically fit are 16V 1000µF. I've never done a cap swap of such a difference, would that even be safe or functional?
Any other cap & I wouldn't even try. Although I assume that because the clock cap is so nonessential for pre-1.6's like mine, I have some room for leeway. Such a difference still sounds insane to me though. Please advise.
P.S. Excuse the photo quality.
