So I want to rebuild my LAN party PC as it's a older PC and ever since I got a new MSI laptop with a i7 7700HQ and GTX 1060 6gb in it the PC has been unused as it's running on a Haswell i5 and a R7 370 4gb. Here;s the part list to it https://pcpartpicker.com/user/SuperM4Tanker/saved/2tTYJx. I'm still debating weather I should upgrade it or just rebuild it into a Sleeper PC in a old ivybridge MATX HP case I have that I got from the flea market in which the motherboard inside was dead. If I do reuse some old parts from the old machine I would probably reuse the GPU, CPU, RAM, SSD, and/or HDD as I can move those over. I can also reuse the PSU as it's a good one but I have some other 500 watt PSUs I can use too that are slightly lower quality and are only regular 80plus rated and not 80plus bronze. My budget if I was building a entire new machine and/or reusing stuff from the LAN PC would be $500, and if I was just to upgrade the old LAN PC the budget would be $200-300. So what should I do????
