Just wanted to get an opinion was looking at the raptor lin 577 vs the lin 581. the biggest difference between the two for me would be the ram the 1 gb in ram vs 512 and the setup fee of $79 vs $29. i will be running windows server on it and was wondering if the setup fee of 79 fo the 577 vs 29 for 581 is worth it. want windows to run smoothly and have read occasionaly about the disk overloads due to not enuf ram. Just want to know if it is really that nessesary. Any help would be great.
