Buying a desktop from eBay Germany vs. local US shops: which is better?

I know you guys are gonna jump down my throat and say I could build something better and cheaper right here in the States—but hey, if some guy in Germany is happy with it, why shouldn't I be?!
Since I’m a total amateur, I wanted to ask the experts: can I put together a rig that matches these specs? Thanks. 🤔

It’s not garbage, per se, but it's definitely outdated. Running a hundred miles on this stuff would be a disaster.

Total garbage for gaming... and honestly, a bit overpriced too.

Man, just look at those graphs 😁 and honestly, the processor isn't any better either. You’re better off staying far away from this one.

That power supply is really intended for office PCs. Could you let us know exactly what your specs are and if you have a budget limit of around $700?

Yeah. Could probably use a better GPU—no clue about the CPU—and a 22-inch monitor would do the job fine enough.

For example,

EVGA 450W Power Supply - Corsair RM Series
MS Knight midi tower case (no PSU)
ASUS Radeon RX Series, GDDR5 128 bit (R7 360 2GD5 OC)
AMD FX-Series X4 4300 3.8GHz, 4MB/8MB, 95W CPU
Gigabyte 970A-DS3P v2.0, AM3+ motherboard
AOC I2476Vwm, 23.6" LED IPS, 1080p Resolution
Sharkoon RushCore Gaming stereo headset with mic
Logitech Slim Keyboard, Ultra Slim, USB, 2-port USB hub
Thermaltake Contac 21 cooler
Logitech B100 Mouse, USB, optical
Western Digital HDD 1TB, Serial ATA III, 7200 rpm
DDR3 8GB (1x8GB) Kingston, HyperX Fury, 1866MHz, CL10

Total: ~$1700 USD
