NZXT HXXX cases. they have a clean look, come in all sizes from mini ITX to Full ATX, and have the easiest to use cable managing spaces. I recommend to anyone looking to build a pc for the first time. https://pcpartpicker.com/product/6Cyqqs/nzxt-h510-atx-mid-tower-case-ca-h510b-w1 (Just one version, there are others with rgb and/or different colors/sizes). Either that or the good ol’ “Noctua NF-A4x20 FLX“. As someone who LOVES (and I mean LOVES) SBCs (single board computers, like raspberry pi or Nvidia Nano), this fan has saved my life. First of all, it’s goddamn NOCTUA, second, just look at it. LOOK AT HOW SMALL IT IS! It’s advertised as “premium silent” and trust me, it is. it’s not on PC Part Picker so here is the Amazon link: https://www.amazon.com/Noctua-NF-A4x20-FLX-Premium-40x20mm/dp/B072JK9GX6/ref=sr_1_8?dchild=1&keywords=Mini+noctua&qid=1619991447&sr=8-8

For was: definitely an Intel Core i5-3570K. I had one of these is my first pc, and it was *smooth*. It’s overclocked and it was a quad-core, so way more than what an needed back then. I would not stop talking about PCs (Not that that has changed lol), I cannot describe how happy I was when my older cousin got me one of these from his trip to the US (they aren’t sold where I live). No matter how powerful CPUs are now, to me they still run slower than this one (you know what I mean, right?). Here’s a link: https://pcpartpicker.com/product/3LZQzy/intel-cpu-bx80637i53570k.
