Seeking advice on PC purchase for Skytrak TGC

Hi everyone. Looking to buy a PC for Skytrak TGC.

According to their site, these are the minimum requirements:

OS: Windows 7, 8, 8.1 or 10
Processor: Intel Core i5 or equivalent minimum; Intel Core i7 recommended
Memory: 4 GB RAM minimum; 8 GB RAM recommended
Graphics: NVidia GTX 670 or AMD 7850 w/ 2 GB (or better) minimum; NVidia GTX 970 recommended
DirectX: Version 11
Network: Broadband internet connection
Hard Drive: 20 GB available space
Sound Card: DirectX 9.0c compatible

Anyone know where I can buy one prebuilt for a reasonable price? I don’t need anything that’s overkill as this will be it’s only purpose.

Maybe the odd Rick Shiels video as well...
