Buying new computer and need suggestions

My dell e6410 laptop has been giving me headaches…so I’m going to go for a desktop, keyboard and mouse…I haven’t a clue as to what type of computer to use(pc though)…by that I mean there must be a computer that works fast and smooth with cubasele8…by that I mean having 10 third party instrument plugins and 50 or so third party effects plus can it reproduce sound real good, not get hot, not freeze up after a half hour like my laptop does…more or less between$400-600 preferably refurbished and SSD with 256 or so gigabytes…Open for suggestion…
