Gimme some input on my computer choice

[DeeBye]

I'm going to be buying a new computer for myself in the next few days as a birthday present. I'm going to be buying a pre-built from my favourite local mom 'n pop store because I was searching various Canadian retailers and can't save myself any money by building it myself. In fact, it would be at least $100 more if I tried that.

Anyways, here's what they will build for me.

CPU
I want to go with an AMD Athlon64 processor. I'm not quite sure which speed I will be deciding on, but here's what the price breakdown will be:
3000+, add $0
3200+, add $40
3500+, add $100
3700+, add $110
3800+, add $200

Motherboard
MSI K8N Neo4 nForce4

Memory
OCZ Premier 1GB DDR 400 dual channel kit

Case/PSU
Antec SLK1650B w/ 350W PSU

Storage
WD 200GB 7200rpm w/8MB Cache SATA II

Floppy Drive (even though I have never used one in at least 5 years)
Sony 1.44MB FDD

Optical drive
LG GSA-H10A 16X Dual Layer DVD Burner

Video card
Sapphire Radeon X550 256MB PCI-E

Onboard 7.1 sound
Onboard NIC
Logitech Internet Keyboard
Logitech Optical Wheel Mouse
Logitech X-530.1 Speakers

I know that the Radeon X550 is kinda lightweight for this system, but my shop's current lineup doesn't include anything beefier for this configuration. I don't do much heavy 3D gaming right now, but if the X550 performs at least as well as my current Radeon 9600XT 256M AGP I'll be satisfied for now until I get a deal on something nicer.

Does anyone have any issue with the quality of the parts, other than the video card?

I'll probably just go with an Athlon64 3000+, unless someone can give me a very convincing reason to upgrade it. For point of reference, I'm still happily using an Athlon 1700+ :)
