I took the power-supply apart and painted the outside black. For the sleeving I chose black and red, this was the first time I ever sleeved anything so the result was not ideal.
It ended up like this when everything was installed.
I bought a 92mm red fan for the CPU-cooler for the hardware I had back then, this build had many different configurations of hardware, for example, I brought this PC to Dreamhack Winter 2010 and then I installed my main PC into it so I could play some games, but what I ended up with in the end was this, some old Socket A setup.
