Almost anything will do if you're mostly looking to watch videos and do basic college work. I'd look for a dual core CPU and somewhere in the 2-4GB of RAM (I wouldn't go lower than 1GB) and not running Windows XP. If the only things in your price range are running XP, I'd very much recommend installing Linux on it now that XP is no longer being maintained in any way. You may also want to hold back or just try and scrape together a little bit of additional funds for an actual video card. Most of the systems in your price range will probably be old Core 2 Duo level systems with very weak integrated graphics. Even a $20-$50 video card would put those to complete shame and would probably have hardware decoding abilities for a lot of popular video formats.
You could also check Freecycle and Craigslist. In a college town, there are undoubtedly plenty of people with old computers who might even be willing to just give them to you if you went to their place and take it away. The downside to this is that there's no warranty of any kind if the hardware goes bad, but the upside is you didn't really pay much (or possibly anything) and often times the specs will be quite a bit better than what you'll find on a manufacturer's outlet site. Just another option to consider.
Just keep in mind that you've got a very ramen noodles level budget, so set your expectations accordingly. Watching videos and doing some light word processing or web browsing might be fine, but in your price range almost anything else is probably asking too much.
I need to get a new refurbished desktop, mine is old and needs to be replaced. I use my PC for streaming videos, and just general work from home stuff. I just need something good enough to stream videos and not run too slow. I like playing games on my PC, but that's not very important to me anymore. I quit WoW a few years back and haven't done much gaming on my PC since. I'm very short on funds, I know it's worth it to pay more. However , I'm a struggling college student and spending over $300 on a PC is just not a possibility. I would like to keep it in the $200 range if at all possible but can go as high as $300 if I have to. I don't know exactly what specs I should be looking for. Like I said, streaming video is my number 1 priority. I do not have cable, I only watch movies and tv shows on my PC. Does anyone have any suggestions for a good refurbished computer in my price range that will do what I need? Any help is appreciated. I have browsed refurb pc's on manufacturers sites, but just don't know what all I need. Thanks so much in advance.
