Any foreseeable problems with the following hardware?

AMD Athlon II X4 640 3.0Ghz CPU
ASUS M4A88T-M Mobo w/ onboard ATI Radeon HD 4250
Silverstone Strider 500W PS
Kingston 8GB DDR3 1333 ECC Memory
Intel EXPI9301CT NIC
4x Samsung EcoGreen F2 1TB 5400 RPM

Thanks for the comments and Happy Thanksgiving!
 
Do you really need raidz2? If not (and only you know), you can get 50% more usable space by going with raidz1. 4 disks in raidz2 will have same write speed as raid10, but slower read speed, although somewhat more redundant, since you can survive any two disks failing.
 
Just from what I have read, Z2 seems to provide an optimal mix of speed and redundancy.

This is for a home server. Nothing terrible fancy. I am currently running a RAID 1 system with 2x 500GB drives with 100GB left in free space. Z2 will give me nearly 4x server space but a lot more redundancy.
 
Like I said, only you know what your job mix is. Read speed from raid10 will be faster than raidz2, but that may not matter to you. In general, I agree with your assessment.
