New Desktop Build Recs

My desktop wouldn't power on yesterday, so I did the quick paperclip test on the power supply without any luck. Ordered new power supply and hooked it up today and the motherboard lights up for a few seconds then shuts down and repeats the cycle. I assume it's fried also. This is a computer I built in 2011, Intel i5 2500k, MSI motherboard, Patriot Gamer memory, cheap video card.

I's like to reuse my hard drives, card readers, case, dvd drives, but I assume everything I listed above will need to be replaced.

I haven't been keeping up with computer tech since then, so don't want to get caught off guard ordering things that aren't compatible. I plan on sticking with an i5 processor, but am open to motherboard and memory manufacturers.

Computer is mostly used for home office type of stuff. Have had some pretty intense Excel files, but no CAD or gaming. Also use it for my Christmas display using xlights.
