Which one? There are 3 blue ones.... lower right is a DELL someone gave me after an a new purchase, (they were gonna throw it out, so I took it). Haven't tried it yet.
Next one to left is a Blue Chieftec (Dragon, I THINK), has the front optical bay door snapped off. Has a working ASUS A7V8X with an AMD 2400+XP (It MIGHT be a 2600+XP, not sure... It's my second. I fried the first one, and upgraded. Cant remember if I started with the 2200+ or 2400+). Weak point in this machine is the ATI AIW 9600 Pro. The thing starting overheating, and causing all sorts of artifacts, and would lock the screen lots. No HDD in there right now, and no idea how much memory.
Above that is a Shuttle SN25P with a...... a um.... an AMD processor which is a Socket 939, but I have NO IDEA what model is in it. Has 2 Gigs of DDR400, no HDD, and no GPU. Tried to overclock it, and fried something on the mobo or CPU, so I bought my current setup (well, bought it in it's base form with a C2D, and 1 HDD).
Sorry, this collection of computers was either built by me, or given to me by friends & family that were going to toss them, so they called me. I don't buy old stuff, just store it.... for..... well, I haven't figured that out yet. LOL.
