Yo! This is a sick set up! Hope you really enjoy it.
2 things though.
Ideally you don't want the tower on the floor/carpet. For dust and thermal reasons. I would strongly suggest getting a stand for it. Super cheap. Easy buy. Something like this

Lastly, this is pretty obvious but def don't blow smoke towards the tower. It will build up in the components and become brown and dirty. I know because I also vape next to my PC.
Just wanted to point out those little things. Hope you enjoy the master race man. I know once I got my PC, I never looked back at consoles. What game you download first?
This little guy right here. Make sure you measure my case is suuper small and there isnt really much more room to spare

I use this height adjustable computer cart to keep my tower off the ground. I bought a cheaper one first and it was too small/flimsy. This is much sturdier. I’m happy with it for both sitting and standing.

Amazon has a bamboo show rack that works really well. There is also the rolling pc cart I linked above. Very small and compact.
