Is my build okay?

Case: Antec Sonata III 500
Power Supply: Antec 500W (came with case)
CPU: Intel Pentium G3258 (stock cooling)
Motherboard: MSI H81M-P33 Micro ATX LGA1150
HDD: WD 500GB
RAM: Corsair Vengeance LP DDR3 8GB
Video Card: EVGA GeForce GTX 750 Ti

I know the case is old but I wanted to know it this will work. Thanks

Looks like it would be good, but you need to confirm memory is a good match for the motherboard at https://us.msi.com/Motherboard/support/H81M-P33.html#support-mem

ps I have an old Sonata and like it - but may have electrical issue with USB on front of case due to 'shiny' (and conductive) plastic surrounding the ports.

If you're not in any hurry then it may be worth waiting for Kaby Lake as those desktop pentiums are rumoured to finally be getting hyper-threading (the mobile ones have already had it for two generations) which should make a notable performance increase in gaming.

I'd also go for an RX 460 over a GTX 750ti as it's faster for the same price, and gets Adaptive Sync (freesync) support.

It's worth looking at SSD prices. A 250GB SSD isn't much more money than a 500GB hard drive.
