Yeah, newegg had a bitchin' deal on it at $1250
I think I know why you chose the way you did. You basically wanted a laptop to act as a small footprint desktop. That drive bay thing would confound me a little though. If I was expecting performance out of the thing, I think I'd at least want to be able to run a pair of drives in RAID0. It's still a bottleneck... but twice the speed is noticeable. That's especially given Windows has such a nasty habit of writing unnecessary data to swap space. This machine is noticeably more "perky" running on a RAID0 array of relatively inexpensive drives.
For various reasons, memory speed probably doesn't matter that much. I could go into it, but won't.
From what I understand, you can DYI yourself a solution to hang two drives. I think Ted is right. They'd have to prove you screwed it up to void your warranty. I'd have to bite my tongue if I had to jury rig a new computer though.
Or you could just live with the machine the way it is. It's sure not a slouch. Unless you are routinely handling big files, it won't matter.... sorta... the operating system response is also improved enough to notice.
If you are going to run a laptop at 100% CPU for any length of time, you probably want a laptop cooler. It might not melt, but cooler is better.
Looks like a neat machine. Real aluminum.... sexy...
My laptop is a weaky, squeaky 5534 with an L310 dual core processor. I use a desktop if I need the juice... One of the Acer promised
things was a high capacity battery. A year and a half later.... still nope... I have had zero problems in more than a year and a half. The laptop is very used. What has sort of surprised me is the way the cosmetics have held up. Very good. This machine probably will just get used as-is. It's slow, but it's good for watching movies, skype, email..... lightweight stuff like that.
I've also been looking at the falling price of velociraptor drives lately. Single or in a RAID, they really are fast. Faster than my 2 drive raid in quantity one by about half again. Supposedly you're supposed to transfer 75MB a second from anywhere in the platter. The stock drive would likely be in the low 20's.
This 450GB drive looked tasty:
I think the hard disk is probably the most noticeable upgrade you could do to a machine in this class. It may be the only upgrade that would be noticeable.
