What Linux Hardware Upgrades Make Sense? - page 2
Memory and Storage: Easy Peasey
For the really ambitious there's the rip and replace option, where you tear the guts out of your machine and replace the motherboard and CPU. This is a more difficult, finicky task so it's not for everyone, but it can significantly upgrade your computing experience. Be careful with big-name computer brands like Dell or HP, because they customize their machines in ways that make them difficult to upgrade with off-the-shelf parts. There are multiple on-line vendors specializing in providing upgrade options for the do-it-yourselfer.
Memory and disk drives are probably the two easiest upgrades to consider from an installation perspective. Just about anyone can do the hard part with a little instruction. The web is full of tutorial videos on upgrading your system. A quick scan on Youtube.com should do the trick. With costs continually dropping, now's a great time to get it done. Go ahead; you know you want to.
