So what are the differences between the large and slim?
This is what it says about the 530s
Slim and stylish desktop design for everyday computing, taking up 41% less space than the Inspiron 530 without sacrificing any features
Probably doesn't provide many options for future upgrades like adding a second DVD Burner and may require more specialized PCI cards for gaming or sound enthusiasts that are harder to come by. I believe they are called "half-sized" pci cards. However, it will take up less space if space is an issue with the size of desk you use, or maybe you live in a small apartment. This type of style probably can be layed on its side, or stood up like it is pictured. Read on...
This is what is says about the 530
Value and reliable performance combined for everyday computing. Highly customizable and expansion slots allow for future performance upgrades.
Meaning that there is more room to umm say for example, add another DVD Burner, or the motherboard is probably an ATX and NOT MICRO ATX form factor which would have more PCI Slots on it for adding something like a sound card for those who are "audiophiles", or possibly a dedicated Graphics Card used for Gaming. Furthermore, it is just overall bigger and probably would be better suited for sitting on the floor, or if on a large desk it could fit, but it would take up more room.
This is all from personal experience, I have never seen any of these in person or had a chance to take a look inside to completely confirm everything I just said, I just know that is the case from other models I have dealt with.
what is the difference between Vista 32 bit and 64 bit?
The main difference is that 32bit Operating Systems can only recognize about 3.2GB of RAM whereas 64bit can recognize just about whatever the motherboard can handle. I think the actual GB of RAM recognizable by a 64bit OS is like 128GB or so from what I have read in the past. Which is insane...
I would say if you are not going to be video editing a lot or you are not a "Gamer" then you have no need for a 64bit Operating System.
So should I call up Dell and ask for the deal that I previously mentioned the other day?... Dell is currently selling a $500 Insipiron 537s with 19" monitor. It's worth it? Good value?
I don't think you should do that. I noticed for the first time earlier tonight that system is an "Open-Source" computer which I believe is Dell's way of saying that
it comes with no Operating System like Vista or XP because there are free OS's available, but since you aren't into all the different kinds out there and don't know how to use them/familiar with them, I wouldn't recommend going that route. Just stick with Vista (Microsoft Windows Operating Systems).
If you could provide an actual link to the one you are strongly considering buying, I can give you a break down or confirm what it has or if that meets the requirements that I have been talking about in this post.
Like the processor, hard drive, RAM. Etc. What Operating System it has. On and on...
Let me know what you think.
