I have always found that vector works great on old pcs, even old laptops. Its great to get more years of use out of something most people would
think is useless. I've found quite a few computers in the trash that with some upgrades and work, made great surfing machines or game machines with dosbox installed.
If you search a bit, you can find ram upgrades, hd upgrades and that sort of thing on ebay for older pcs and laptops...
I have an older sony vaio that is going to get vectorized next week. Its got a 1ghz processor, but has a dvd-r/w drive I installed, and more memory.
Nice big screen too, should make a great machine for vector.
Welcome to vector linux btw...
