I have a budget of 800 dollars to make a solid yet mobile gaming pc. No OS needed but I do need a keyboard and mouse.
PCPartPicker part list / Price breakdown by merchant
Not small, but it fits in the back seat of a car, and has a handle. You can substitute the RX 590 for a used GTX 1070 if you want PCPartPicker part list / Price breakdown by merchant
Are you sure it will fit on that Case? I just wonder...
it fits, the message is just because it doesn't have GPU length recorded, it's the same length as the RX 580 GTS XXX
The length is not the problem. The problem (if...) would be the 2.5x slot design!
should be fine as there is enough space
Well, then OK. :)
