it’s true of you already have atx and you need to buy a sff psu. But there are a couple companies coming hard to the sff market. Cooler master has cheaper high power units out now and are said to be bringing kits. Case psu and AIO
How small are you looking to go? Give a range. < 10L? < 15L? < 20L?
The most popular bang for the buck sff case is the cm nr200 for $100. Is is on the larger side at 18L but being bigger means you won’t need specialized parts, cables etc. Good for entry into the SFF hobby.
There are certainly some boutiques that still do full size cases still. Although many seem to go full CNC and thus gets very expensive.

Are i7 970s considered some of the worst hex core X58 silicons? I see everybody with X5650+ get lower voltage and high frequency. My 970 does 4.3 (187x23) at on 1.4v on R3F. Maybe I need to ditch this and pick up a X5675. Hoping for 4.5ghz
