PC build for my kid - looking for advice

Hey everyone.

So, I’ve been scouting out gaming laptops and my budget actually allows me to
pick up one with an Nvidia 960m graphics card inside.

That kind of rig can handle WOT and plenty of other games he
likes to play. It’s a solid choice since he can just lug it over to his
mom's place or take it to his grandpa's for the weekend. A 17" model is sitting at about $1,100.

But now I need a separate desktop setup so that when he isn't around,
I can jump on and play a few games myself.

It's been ages since I dealt with this stuff and the options are totally overwhelming. Could you guys help me put together a gaming build with the best bang-for-your-buck ratio? My limit is $900, and that needs to include a monitor that's at least 23". An SSD is a total must—I don't care about a standard hard drive because I've already got several 2.5" external drives for storage.

Thanks for the help!

If you need more than 256GB of SSD space—since you're relying on external drives right now—the price jumps to $7,300 with a bigger drive. Or we could drop the cost by picking a weaker GPU... depends on what you actually need. (EDIT: ignore that last part)

EDIT: lol, where's my power supply? 🙈

Need to add a power supply to the list too (extra $142):
-500W FSP Fortron/Source Hyper power supply, ATX 2.31, HP500, PPA5005003

If $2428 is too much, we can scale back with a cheaper graphics card.

I'm guessing the power supply might be tripping at the CPU 😛
