First Time Computer Build - Any Good? Basic Use

[24JS]

Looking to build a computer for basic home use. I don't play any video games, moderate multitasking with music and surfing the net. Enjoy watching movies on my computer but not primary use so I opted out of a video card. Will connect my current wireless router directly through lan port. About $420, parts from amazon, going to order today I want to stay in this price area. Used PCPartPicker for part brain storming

Let me know what you think. Any issues/suggestions, anything extra i should get (absolute necessary)?

CPU Intel Pentium G2020 2.9GHz Dual-Core
Motherboard ASRock B75M R2.0 Micro ATX LGA1155

It has Intel HD 4000 graphics so it'll probably suit well for what you need it for.
