I have a number of these as a result of doing some upgrades at my work. These are memory modules for desktop computers, pulled from IBM ThinkCentres (Pentium IV HT) but will run in other brands/models as long as the specs match. What I really need for my home PC is some DDR2 240-pin DIMMs, either 1GB or 2GB. I'd gladly trade 1GBs for 1GBs straight up, or 2 x 1GB for each 2GB. Pairs (of either) would be better than singles. These go for around $35 new but if anyone's interested in buying I'll say $20 each (PayPal) and shipping on my dime in the lower 48. Here's a link to a current vendor: PROVANTAGE: Crucial Technology Memory 103484 1GB PC2700 DDR 333MHZ CL2.5 128MEGx64 - CT12864Z335 If you have a computer with 512MB or 1GB currently and can bump that to 2GB or 4GB you'll likely notice a huge performance improvement. PM with questions, etc...thanks.
