would this be a good pc

Solution
It's decent but either go for 2x4gb or 2x8gb memory. Also if you are going to buy a GPU like the R5 250, better don't buy a GPU at all and use the HD 530 (integrated of the i3-6100).
Don't opt for optical drive. Add that money in something like GPU. Also I think WD Blue is cheaper(depending on where you live). That 11 USD you saved can be added to GPU + 10 dollars if you are not that tight on you budget and you can have r7 360. Hope it help.
