For a couple of days now I planned to finally upgrade my desktop computer, which has been in use since 2004 with, believe it or not, the original equipment (!):

DELL Dimension 4700
Intel Pentium 4 HT 550 (3.4GHz, 1MB L2), Socket 775 original
305W PSU, SATA HDD (250GB) original
Dell Motherboard (0M3918) original
IDE DVD+-RW, IDE DVD-ROM original
3GB DDR2 RAM
Thank you, you have done your job!

I know I can consider myself very lucky but sometimes you have to love computers so they love you back.... But I have to admit that in the past few years I've already zero-level formatted my HDD twice and one memory DIMM failed (upgraded then to 3GB).

Anyhow, it's time to make an upgrade, as my S.M.A.R.T. table is full of errors and it's always funny to touch new hardware.
After I decided which new hardware to build into the case (yes, I'll keep the Dimension 4700 case, call me weirdo), I thought it could be helpful to compare some Swiss IT shops. I ordered the wanted stuff from different shops, all at pretty much the same time. Let's see who is the fastest.

Order date	Shop Name	Product	Delivered	Total Days
Jun 5, 7.16pm	TechMania	Intel CPU i5 4C 2.4GHz	Jun 9	3 Business Days
Jun 5, 7.28pm	PC-Ostschweiz	Asus P8H67-M-EVO R3	Jun 9	3 Business Days
Jun 5, 7.34pm	Internet.ch	2x 750GB Seagate HDD	Jun 8	2 Business Days
Jun 5, 7.38pm	PC-Ostschweiz	6GB Kingston DDR3 RAM	Jun 8	2 Business Days

Considered that all products were ordered on a Sunday evening, the next business day (monday morning) should be counted. All products were on stock at the moment of order.

Update June 10: Now I've received all the packages. It took max 3 business days which is a very very good result!

Update June 21: I finally decided not to keep my old Dimension case (due to cooling-issues) but instead bought a new mini-tower case from Sharkoon (AL2).
