My first PC build for ~15 years:
- exchanged Motherboard, CPU, RAM, CD-Writer, Power supply
- re-used Case, HDD
- spent ~240€
- got an AMD A8-5600, 8GB RAM
- ordered at http://www.alternate.at
- followed http://lifehacker.com/5840963/the-best-pcs-you-can-build-for-600-and-1200
- upgrade went extremely smooth, except that i missed the fact that mainboard connectors changed during the last ~10 years 🙂 and i had to upgrade power supply (which i didn’t plan from the very start).
