Building a pc without a case?

[finnigen]

So I am thinking of upgrading my system. I will probably upgrade my mobo to z170, cpu to i5 6600k, ddr4 ram... I also thought this would be a good moment to get a new case, first I was thinking of the Phanteks enthoo luxe. BUT then I saw a post of someone who built his Pc on some wooden planks and hanged that on a wall. I was also thinking of something similar, maybe just something more open. Would this be a bad idea? Advantages/disadvantages? Do you guys think this will be hard to do or fairly easy? What do you guys think.

My other specs:

Case: Bitfenix Shinobi bf4 edition

Gpu: Msi gtx 970

Cpu: amd fx 8350

Cooler: noctua nh-d14

16 gb ddr3 ram

Psu: bequiet 600w

Samsung 250 gb ssd, 2 terabyte hdd

Ps: it is for gaming

Having an open PC Is totally ok, + temps will be better

Just make sure it's well enough protected that nothing can fall on it, spill on etc... Just take the necessary precautions

it'll start collecting dust more than in a case but other than that why not

LTT did a similar video, but just do it on a wall.

There is no problem with making an open system with a home made 'case'. Just watch out for the extra dust buildup and in case you are making it with acrylic parts and putting it on a carpet or something, make sure the mounting screws of the motherboard are grounded to the PSU casing to prevent static.

I don't know, wouldn't dust build up between the mobo and the plank? ->static->dead PC.

Not if you clean/dust it regularly.
