so i'm building an emulation/htpc computer for my media setup in my room and i want to use an old computer tower as the base

here's the prob though, it has little to no airflow and i'm going to be using a power hungry CPU with it (AMD FX-6300)

it's all i really have other than an LGA 775 motherboard with a Core 2 Duo and 2GB of RAM but the USB ports on the motherboard are fried and i would have to use a USB PCI card

so rip me

and i don't want it sounding like a jet engine

perhaps i could undervolt the CPU? like i'm not gonna be needing that much power for emulating older games

"undervolt the CPU?"

no that could cause problems over time, idk man

i would say you're risking heat damage more than fire though

Add as much fans and stuff as you can, get as much air flowing as possible. Given it's lower specs, and the fact that your using it for media streaming, it would probably generate the same amount of heat that it would playing Halo Combat Evolved.

If you can, go for a quad with the 775 socket, de-clock it.

Also, if your using it as a media server, get some more RAM for god sakes.

i was kinda thinking about putting a really stupid emachine or packard bell logo on the side of the case for irony

but then they open up the case and it's an AMD FX-6300 setup

As above said, it's not much of a fire hazard, more a heat hazard. Could cause the board to unintentionally flex and it might pop one or two capacitors

the fan size on this case is 80mm and that's the only fan mount the case has, i guess i'm just gonna have to find a really good yet really quiet 80mm fan. i will probably put a cooler master hyper t4 in the system once i find the damned bracket

"If you can, go for a quad with the 775 socket, de-clock it."
had a Q6600 but sold it a while back :'(
and i would totally be going with the LGA 775 board if it didn't have fried USB, it's a really nice board from ASUS with lots of settings

"Also, if your using it as a media server, get some more RAM for god sakes."
not a media server lol just an HTPC, but i have 8GB of spare DDR3-1866 and that's what's going in the machine

i was exaggerating it, but in some cases (no pun intended) you can actually have a fire hazard of a setup. especially if you're using an extremely cheap power supply, like those bestec power supplies that would eventually fail and overvolt the 5v rail so much that it would fry about everything. but if you get even cheaper you might have to face legitimately explosive power supplies due to negligent designs, which could possibly catch something on fire

"legitimately explosive power supplies"

yo have u seen those foreign power supplies they r like fireworks LOL

they don't even have diodes for short-circuit protection and some of them have a short to ground right out of the box

and the board i'm using doesn't use electrolytic caps so i'm kinda lucky in that regard

even if it did i'm sure msi wouldn't have gone for cheapo/crapxon/gsc/jamicrap/rulycon

one time i opened up a (seemingly very cheap) power supply in an old sempron prebuild from around 2004.

the gauging of the wires was alarmingly thin, heatsinks were almost slabs of aluminum foil, absolutely no filtering, caps were about to explode, solder creepage couldn't pass any safety certification if it tried, and the entire layout of the power supply looks like a mediocre ATX power supply from 1998. really overpowered 5v rail and almost no amperage on 12v rail.

this thing claimed to support 450 watts LOL

oh yeah and the primary transformer was maybe a bit over the size of your average dice cube

i've actually accidently exploded many electrolytic capacitors usually due to reverse polarity, and when they explode (assuming that they don't have the v-shaped indents on the top) it looks like a legit tiny firework

that's a fun way to deal with spare caps that you have no means of keeping around though

i love playing with microwave oven transformers, they're like your average pcb transformer except they are 10x bigger and output around 1100 watts
