In the current climate, with global shortages and such, building a pc that's a good value or bang for buck, is kinda tricky, especially if you're trying to build a gaming pc. However, someone asked me to build them a gaming pc, and wanted it sooner than later, so availability checking I went.
The biggest problem was the GPU, what video card could you get for a relatively decent price that would be good for gaming? (and fit within the customer's 1000 euro budget, yikes). Eventually I managed to get my hands on a 1660 TI, a respectable mid range card. I did end up overpaying for it, but hey, I got a decent GPU and did not spend a fortune to get it. (I paid 400 euros for it, way too much if you ask me, but atleast its not 2x the normal price).

The customer also had other demands, the build had to have RGB lighting, okay, 4TB's of storage, why, and 32 gigs of ram for a gaming build.
The RGB lighting I understood, it's alluring, you know, every time you see those crazy builds with lights everywhere.
The 4 TB of storage I didn't really understand, its nice to have, but since there was the 1000 euro budget, it ended up being a cheap SSD boot drive + large HDD combo. Not what I would want, I would spend the extra money on a bigger ssd but hey.
The customer originally wanted 64 gigs of ram, but I explained to them that for gaming, 32 gigs is more than enough.

After having spent most of the budget on the gpu, and spending more on the ram and case than I would have liked, it was time to fill in the gaps with some good old budget parts.
I ended up picking the Ryzen 5 1600 AF for this build. It should be more than enough for gaming, and if the customer every wants to upgrade, they could also buy a decent cooler and just overclock their CPU, since the AF model of the 1600 is essentially a weird 2600.
Throw in a good ol 550 watt PSU from corsair and the same Asrock Motherboard I used in the last build, and boom. You got a surprisingly decent gaming pc.

Now, there are numerous parts that are way better for this kind of build. I would have liked a 3300x instead of the 1600 AF for instance, but even those were sold out. I simply used the parts available, and I think the build turned out pretty neat.
