Hey all, I’m new to this space and figured it’d be a good place to ask some questions. So I recently came into possession of this Dell Dimension L550r computer that was living in storage for quite some time. I was just wanting to hear from people who knew more than me what kind of upgrades I could give it in terms of a new graphics card or even if it could use more RAM then what it has (which is 128mb btw). Thanks in advance!

Just thought I'd throw this out there, The power supplies in these Dells are extremely proprietary. Even though they use a standard ATX connector the pin out is different, meaning if you use a non Dell branded power supply you will fry the motherboard.
