Dinky is my Linux server. It started in 2003 with a Pentium MMX and has undergone many major and minor changes. It is not so dinky anymore at version 7.5. Motherboard, CPU, and SSD were gifts from a very generous friend. Right now it is still primarily a Linux server running Gentoo, and also a HTPC running Kodi. The video card requirements were to have VDPAU and run Minecraft if needed. Latest additions were the case and power supply.

I was debating R4 vs R5 for a while then the R4 went on sale. It wasn't long before I though maybe I should have went for the R5. The first factor was I wanted to replace the clip-on fan with a Hyper 212 and found the rear motherboard opening didn't go down far enough to remove the backplate. Would have had to remove motherboard. The second was I couldn't utilize the SSD mount behind the motherboard without removing the motherboard. Both of these factors are fixed in the R5.
