There aren't many places in Berkeley to get computer parts, I mean sure many places have the basics (blank CDs, mice, network cables), sometimes you need a more obscure part. Or maybe that old clunker finally died on you. If you need random parts, go to the Used Computer Store. Maybe if you want a cheap computer, you can go there, or if you want something fixed. If you're buying anything that you could get at Best Buy, then go to Best Buy. The prices here can be steep for no name products that were obsolete a decade ago.
