Budget gaming build advice. under $500 or cheap as possible

[Sparkynutz]

I have an old I5 4590 build.
I have been using a newer acer aspire laptop but want a desktop again for light gaming.
Warcraft 3 and Starcraft 2.

My old parts I'm thinking of trying to use
NZXT source 220 classic case with a buttload of fans installed.
Antec 650 true power classic psu
Crucial Mx100 ssd
Evga Gtx750TI

Parts I most likely cant use-
Asrock h97 motherboard
Hyper x fury 8gb x2 240pin ddr3 pc3 12800
I5 4790
very old 19" acer pos monitor.

I'd also like to pick up a new 27 or so inch monitor if budget allows.
Need windows 10 or see if I can upgrade using my old xp cd key

The parts, especially the i5 4790, will be ok for Warcraft 3 and Starcraft. I'd say put them together and check CPU/GPU load (with MSI Afterburner or similar) for performance bottlenecks. If you want to spend money, I would rather invest in the GPU, as the 750Ti is way below recommended system requirements for Warcraft 3.

Windows 10 cannot be installed using a Windows XP key. There was a short time period where you could upgrade from Windows Vista to 10 and keep the activation, but nowadays only Windows 7 or later are possible.
