Building an office desktop

[AndreCosta98]

I'm building a budget desktop pc for my parents. They work as secretarians and don't have a pc at home. What is the best budget choice possible? I got a bunch of stuff from old pc's. This is what I have:

power supply - lc-8500btx
CPU Cooler - Heatsink Fan Skt 478 C33224-002
ram- some kingstons ddr3 and 2 hyper X fury DDR4

the motherboards i have are really old. I don't think I'll be able to use them.

If anyone can suggest a good budget build I'd apreciate, If I could use the DDR4's I'd apreciate that as well!

Few words
Build itself is micro-ATX due to the smaller MoBo and case used, which is good since in the office, there isn't usually much space where to put mid-tower ATX PC. Since CPU has on-board graphics, dedicated GPU isn't needed, saving a lot of money. MoBo has 4x RAM slots, making any future RAM upgrade very easy (not that it's needed for this build anyway). For storage, SSD is best price to performance ratio and well enough in capacity for OS and additional software. You can remove HDD if you want to save some money but extra space could come handy. Case is standard office PC looking one, meaning no side window. If your folks doesn't use CDs, DVDs, you can also remove the ODD to save money. Also, if PC is connected to the net via cable, you can remove the wi-fi adapter as well. And lastly, PC is powered by good quality and fully-modular PSU.

If needed, that PC can be upgraded to high-end, 4K gaming rig with 3x simple upgrades:
CPU: from G4560 to i7-7700
RAM: from 2x 4GB to 4x 4GB (with 2nd 2x 4GB 2400 Mhz set)
GPU: from none to GTX 1080 Ti (since 620W PSU can handle GTX 1080 Ti with ease)

Here's the same build as above but with all the extras (HDD, ODD, wi-fi card) removed,

Note: to save even more money, you should be able to use your 2x Kingston DDR4 RAM DIMMs, making the purchase of G.Skill RAM unnecessary. With all the extras stripped and when using your Kingston RAM, you can make the whole build sub $300.
