hi all, I am planning for my surveillance system and going to get blueiris as my NVR system. Tossing between if i should just build a new ryzen 3200g with a320 micro board with 8 or 16gb ram, 240g ssd. About $550-ish with micro case, going to reuse my power supply (6yrs old) from an old build. Price ex windows yet. Or maybe just buy new power supply for another $60. Or should I just save the hassle and buy a used HP or dell SFF with i7 6700 which is about $499-$599 range with Windows 10 pro. I guess with new build I get warranty while used pc depends on luck it can last forever or not. Have anyone got similar experiences? What's your thought on this? Trying to keep as budget as possible since it just NVR and nothing else. Feel like to provide feedback on any pc parts that I should get instead. Thank you so much.
