You might also look at the Kingston V200 SSD. It can go on sale for as low as 75$ for the 128gb version and they improved the performance a lot with the new firmware (which it should come with).
Other then that I suggest maybe a mechanical keyboard with cherry blue switches. You can buy Filco's from NCIX or an
RK-9000 from newegg which is 79$ right now.
Also, the Antec 300 is a pretty decent case but if you want to go cheaper I would suggest getting a
Bitfenix Merc Beta for 29.99 on sale. I bought it for a spare parts build for myself a while back and was pretty impressed with all the features and room it had for everything.
