Assuming in the US... It's not horrible, price-wise, BUT...
- The 980Ti performs around the level of the 1660 or 1660 Super, but consumes twice as much power. That it is used and thus no warranty means I'd value it at maybe half what a new 1660 Super would go for.
- The CPU is available new with a full warranty for $85.
- The motherboard is $55 new. A cheap one on the A320 chipset that MIGHT limit upgrades to the 3000 and 4000 series CPUs.
- The RAM is slow for a Ryzen system, faster RAM new in the same amount would be something like $75.
- The combination of 500GB HDD and 60GB SSD sounds like leftover parts. A 1TB HDD on its own would be better, or a 500GB SSD.
- The power supply is "okay" - but with that video card, I might want either a higher-quality model, or a higher powered version of the CX or CXm.
Here's a parts list that would cost about $200 more after rebates, but is all new, better quality stuff, faster RAM, storage is an SSD, power supply has a little more headroom, and has full warranty.

HOWEVER - I am not clear on whether you're getting a case, keyboard, mouse, and
valid Windows license with that parts list you mentioned. Any of those, particularly the Windows license, has at least some value, and, thus, is worth considering.
