Wow, I can't believe you people are recommending keeping that powersupply... then once it fries and takes the mobo or gpu with it, there will be the influx of 'you should've used a better powersupply' responses.
My thoughts... Your powersupply is the backbone of your system. If you go with a crap, 3rd tier brand name powersupply, you should expect the potential problems that come with it (as well as the financial risk tied to it). Good luck op, but I wouldn't want my house foundation built out of mud rather than concrete (if you catch my drift).
If I were to but a new one (i have absolutely NO problem with buying a $25 cs430 or even a $80 seasonic) would it fit in the case? I remember hearing that the dell cases use non standard parts, right? Maybe I could take the psu out and take a pic of the case to see if it'd fit. Couldn't I technically just put it in anywhere even if it doesn't fit the case exactly? Like I could just have it sitting on the side of the case instead of indie, lol if that would work that way.
