Here’s a system that I built recently:
MotherBoard: MSI K8NGM2-FID GF6150 939 $76.99 (onboard graphics and gig networking is key - it’s only a slave but you can add a graphics card afterwards.)
Memory: 1Gx2|CORSAIR Twinx2048-3200c2pt $208.00
PSU COOLMAX|CXI-450B RT 1 $52.50 (part of the processor bundle - I recommend the ANTEC Truepowers instead)
DVD+/-RW NEC ND-3550A BK % 1 $28.99 (dont even really need a DVD writer or a cd drive for that matter - you can take it out of one comp and temporarily use it to do your installs)
CASE ANTEC|P180 SIL RT $114.99 (IMO the best case on the market - super quiet and good airflow - the PSU above didnt stretch properly for this mid-tower so I ended up buying bought an Antec Truepower instead)
CPU AMD|A64 X2 4200+ 2.2G 939 1M R $183.00
HD 160G|SAMSG 7K 8M SATA2 HD160JJ R - OEM $54.99
These all fit together except the powersupply/case - wasn’t expecting that. You can go with smaller case or with a longer cabled PSU. Again, you can save on the CD drive, hard drive by going lower, different motherboard, lower or cheaper memory, and case by getting something smaller. Don’t forget you could possibly recycle old parts too. I suggest looking at neweggs ratings, and the quantity of people rating each item.
Abbreviated instructions (don’t hold me responsible lol):
1) Screw in the PSU - easy.
2) The processors fit like a key. You lift a lever, drop it in, lock the lever, put the fan over it which locks in. Don’t forget to remove the plastic from the bottom of the CPU fan and discharge any static you may have on your fingers.
3) Take the memory and match it to the slots (like a key.) Put the 2 memory DIMMS in the same colored slots. Screw the motherboard into the case - make sure that the holes line up with the pins on the case. If there’s extra case pins that would touch the motherboard where there aren’t holes, just unscrew them as that could cause a minor short.
4) Connect the hard drive -very easy. Two connectors - one from the power and one from the motherboard.
5) The trickiest part is just reading the manual diagram and connecting the case wires (LEDs, power switch, reset switch) to the board. The diagram shows you where they plug into. Sometimes you have to reverse the pins after booting when you see they dont work/light-up properly. But really that’s not even difficult.
6) Once you get all the stuff connected, you just turn on the power and throw in the Operating System CD. Let the install proceed. This is a Nvidia-based chipset board so I downloaded the NForce 4 platform drivers onto a cd. Once booted up, I installed the Nforce platform drivers and everything works fine. Connect it up to the network, install basic software, raise virtual memory, turn off Windows screen effects (I used classic interface without fades and whatnot to conserve memory), put the vrayspawner into the start menu, and done.
