I recently acquired an unwanted Dell Dimension 4600 from a friend and it happened to be the same model to what my family used back in the day (around 2005). For this reason I decided to give it some love instead of stripping the parts and throwing out the case especially as I found out the case supported standard mATX boards despite being OEM.
I also decided this would be the perfect case for use as a test dummy to practice using carbon vinyl wrap on before I attempted it on my main rig. I used 3M Carbon Fibre Vinyl wrap to cover the original light grey parts of the case (somewhat improving aesthetics but also ruining the original look which I kinda regret). I did keep the Pentium 4 and XP sticker intact though.
I might as well run through the parts to explain why this build is cheap as it is:
CPU: I found a cheap Q8400 at a car boot sale and for £5 ($6) it was a steal IMO.
MOTHERBOARD: I needed a cheap 775 board with 1333MHz FSB and reasonable overclocking and ebay helped me out providing me with the board and stock cooler for £10 ($12). Nice board but only capable of 4GB RAM max unfortunately.
MEMORY: 2 x 2GB DDR2-800 for £8 ($10). Decent.
HDD: Salvaged from broken Sky HD box. Suprised it was WD.
GPU: Cheap from ebay as plastic shroud had fallen off. Nothing super glue couldn't fix. Decent performance especially for price about equivalent to an R7 360 for comparison. Blower style cooler really helps in a case with no chassis fans.
PSU: Another cheap car boot bargain. Plenty of reliable juice and 2 PCI-E connectors.
OPTICAL DRIVE: Salvaged from another old PC. Faster than original dell drive. Can now play my old games on CD once again.
Overall i'm pleased with how this turned out. Big ups for dell for making such a solidly build case back in the day with surprisingly good features like a screw-less side panel and a single low profile hard drive caddy. Gaming performance is reasonable even on newer titles like GTA V and Rainbow Six Siege. The temperatures were surprisingly low considering the lack of chassis fans.
This PC will be used for playing my old physical copies of games and a spare computer for friends to use when they come over.
I hope you liked this build. Please feel free to criticize it ;)
