I list the prices of the most important components for your calculations. 2 PIII/933 $500 1GB SDRAM(4x256MB) $450 MSI 694D VIA Dual Socket 370 motherboard $140 40GB ATA100 Hard Drive (7200 rpm) < $150 others: monitor, video card, network card housing, mouse and keyboard So, you can build two dual PIII/933 w/1GB memory Linux machine as I suggest. Of course, you just need one monitor for them. You can remote-control them when you run QM jobs on them. Remember, this type of computer is very good for DFT calculation. Don't try POST-SCF calculations (ie CCSD) on them, or you will be very disappointed. I hope my suggestion gives you some help Sincerely Yubo Familia Esguerra Neira wrote: > Hello all, > > I would like to ask for your advice on buying a PC for running gaussian 98 > and gamess-us jobs under Slackware Linux 7.1.
