My computer used be in my dad's old Gateway case. It was pretty ugly and didn't have very good air circulation. I decided to make my first custom case. I saw somebody's computer who had their computer on the wall, on some other forum, and he said it was almost silent and it looked pretty cool. I then decided to build my own case wall computer thingy.
AMD 2100+ Tbread OC @ 2gig
BioStar M7NCD Nforce2 Motherboard
Creative PCI 128 Sound Card
Albatron MX440-8x 64mb 128bit 360/460
Maxtor 40 gig HD
some other 40x cd-rom drive
256mb of Kingmax 433 DDR
350 watt PSU
this computer is super quiet. I've done the 5 volt mod on the CPU & GPU fans and you cant hear them unless you put your ear right up to them. The harddrive is very queit also.
I took the casing off the PSU and cut an old AMD heatsink in half and slapped it on both of the PSU heatsinks. I have been running this PC for about 4 months now and haven't had any problems
i have also done the duct mod on the CPU. It gave me 5C cooler. and it also made it a little quieter.
Temps are: No load = 32C 100% load = 41C
here's the pics
now all i need is another stick of ram and some rounded IDE cables and i'll be set.
