Getting ready for a fakin' new pc. I know all the parts I need to get but the PSU and maybe a computer case, DVD Writer and GPU. These are the parts I'm hoping to get: CPU: Intel Core i5 4670K (3.4GHZ-3.8GHZ/Quad Core) GPU: Intergrated Graphics of the CPU, I'll buy one later, only hoping to play old games. Mobo: GIGABYTE GA-Z87X-UD3H (has the LGA 1150 socket) RAM: Corsair DDR3 1600MHZ 8GB (x2-4GB) HDD: WD- 1TB/6GB/s/7200RPM 64MB Cache SATA Yeah, so do these all match up? Like will it work together? If it will then great. A PSU, DVD Writer and a computer case is what confuses me. The current computer case I have has a size of: Will all the parts fit in this case? I have a DVD Writer occupying this computer right now, it's the Samsung TruDirect SH-S223. Will this work with the new parts I'm getting? And yeah, this fits in the CPU case I showed previously. And then the last part I need, a PSU. I don't know how do I check to see what PSU I need to buy. I saw these PSU calculators on the internet, I tried one but it's a tad confusing for me. If you guys answer these questions I'll be greatly appreciated, thanks!
