My laptop died, so I decided to build a desktop as I also decided to switch from console to PC gaming. I researched the components online for a few weeks, and this is what I came up with.
This works for me as a decent budget gaming rig.
The Hitachi drive was salvaged from my laptop. It's got a Linux OS which I use just for web browsing and streaming music. I use a HD Sony TV as a monitor. I'd got a mouse already, and I bought a generic keyboard for £3.23.
I'm very happy with the components, and it was great fun to build my own PC. Having four drives meant the cabling was tricky to keep tidy, but I've seen worse.
The optical drive spoils the look of the front of the case, but it's a necessary evil. Maybe white paint is the solution....
[update] I've come to my senses and removed the optical drive. Photo added.
