Now this is cool. I actually have an old motherboard from the midlate-90's I beefed up. Back in the day it was pretty expensive I bet. It runs parallel (IDE) cable by hard drive, but has 2 ports for serial ATA. The original Hard drive was 32GB.
It's built for Windows XP, but I could probably run 7 Home Premium. Like I said tho, I beefed it up a bit and gave it a 250 GB serial ATA Hard drive, 2 GB of DDR1 RAM (Motherboard doesn't support DDR2, it's actually pretty old) It's got a Pentium 4 with them crappy embedded graphics (that were revolutionary at the time) "Intel Extreme Graphics"
Anyhoo, it runs Blockland pretty decent for the most part. Of course I have to turn down some settings and switch the reduce-render method up, and you can't really run more than 30K bricks before the real lag hits. It doesn't really help that I don't have any thermal paste so I am using 40% zinc oxide diaper rash cream "ass putty" (look it up) on the processor and heat sink. Ima go and get some pics of it and get an in-game vid for FPS testing
