Question First time home studio build - any advice/opinions welcome!

I would definitely get a better PSU - that unit you have chosen is rather low end even though it is from a reputable brand. I think I would also lose the mechanical HD and go all M2 for your primary storage. This would be a much better rig, IMO:

Made some minor changes, to get you an ATX board, and faster ram. Keep in mind, 4th gen is getting announced today.

Looks good, but hold off for a bit: you might be able to get a 5600 for a similar price in a couple of weeks
Yeah thats a good point, and luckily i wont be making any order for these parts until later this month anyway so I will have chance to find that out!
 
Thanks for looking, What would you suggest if you dont mind?

Personally would look for 3600 (speed) and have been quite partial to the "Ryzen optimized" G Skill. I love Corsair RAM in particular but it seems we get a lot of questions here about issues between zen and Corsair. It's never a bad idea to look through the mobo QVL on that.

Interesting thank you! What would be the main benefits of ATX? Others have told me to go mATX as i would only be paying extra for the big metal box haha
 
You have an ATX case chosen, so you may as well go with an ATX board. It will look a bit odd with an M-ATX in and ATX case. You also get more expansion slots, if you ever decide you want to say add a wireless card, or one of those NVME adapters for more NVME storage. The ATX version has a heatsink for the top M.2 slot. It also appears to have a better power delivery setup as well.

Sounds like smart advice. Thanks for taking the time
 
Now if you want something small, you could go with something more like this, for a bit more money. You do lose out on expansion opportunities though.

Im not too fussed over the size really now that im really thinking about it, i kinda think ATX has better a aesthetic quality to it anyway and more room for expansion is always a good thing. The only thing im unsure about now is the psu. I originally had picked the corsair you suggested above, but then quite a few people told me its worth spending extra for the seasonic one. I honestly cant see what the big difference is though to warrant such a higher price? Id prefer to save some money on that aslong as its still efficient and reliable enough.
