My previous build had been untouched for ages and every was very outdated so over the past month I've been collecting parts from eBay and have completed my upgrade now.
The only thing I haven't upgraded for now is my monitor. It will be next!
There is also 2 1tb drives next to the power supply in the caddy I haven't listed.
I had set a budget of £400 + what I could get for selling my older parts. I think in total it was about 800 for everything excluding the monitor as I already had it.
