Vostro 3750 keyboard/memory/hdd

Regarding the Dell Vostro 3750:

Before I place the order hopefully someone can answer the following questions:

1. [MEMORY] My config comes with 4GB (1 dimm). I would like to add another 4GB myself. What memory should I order that will be compatible (dual channel)?

2. [KEYBOARD] The online configurator only has Azerty. Can I get a qwerty keyboard (us or uk) from somewhere? Is it easy to install? Would it void the warranty?

3. [HDD] I've selected a 500GB drive. Is it possible to replace it with an SSD and use the 500GB drive as a secondary hdd? Do I need a caddy? Where can I get one?

Thank you kindly.

Abe

 

Using coupon codes I managed to get a 25% discount on the system, so I went ahead and bought it. The memory is the most important upgrade I need to make. Can anyone help me pick a 4GB stick that will work well with the one that comes with the system? Or should I get a 8GB kit (2x4GB) and just sell the 4GB...?

 

where did you get that sort of coupon discount?>

I was told SSD drives werent compatible with the main board of the vostro 3750 which is what I m getting and also there is no WWAN upgradeability so will have to use a dongle when required. Is this true?>
