First off I'd like to thank everyone for their help. I'm asking for advice because, I can't afford to shell out $200 or more for a good external hard drive. I've been using an HP Pavilion and,I'd like to build an external hard drive with at least 200GB for it. I'm also not an expert on PC's, but I'm computer literate though, so I think I should be able to build one without any major complications. I was able to install my internal DVD writer with no problems. Please someone help me out. Once again, Thank You!
