Considerations for buying new mini PC/firewall appliance to run Snort Intrusion Prevention System (IPS)

Subject: Considerations for buying new mini PC/firewall appliance to run 
Snort Intrusion Prevention System (IPS)

Good morning from Singapore,

My old desktop PC which is running Snort Intrusion Prevention System 
(IPS) is failing.
These are the hardware specifications:

- Intel Pentium Dual Core E6300 processor @ 2.8 GHz
- Intel Desktop Board DQ45CB
- 6 GB DDR2-800 memory
- 1 TB 3.5 inch SATA internal harddisk

I am going to buy a new mini PC/firewall appliance to run Snort IPS.
The price range should be between SGD$200 to SGD$250.
The hardware specifications are as follows:

- Intel Celeron J1900 Quad Core processor (2M Cache, 2.0 GHz up to 2.42 
GHz)
- Intel HD Graphics
- 1 x DDR3L SO-DIMM Socket (Up to 8G, 1333/1600MHz)
- 1 x VGA
- 2 x USB 2.0
- 1 x Mini-PCIe for mSATA SSD
- 4 x Intel Gigabit LAN ports
- 1 x RJ45 RS232COM port

Are the above specifications optimal for running Snort Intrusion 
Prevention System?
I will be installing Snort as a package inside pfSense firewall/network 
security appliance.

Should I choose 2 GB DDR3L + 32 GB SSD, or 4 GB DDR3L + 32 GB SSD, or
4 GB DDR3L + 64 GB SSD? Will I run out of disk space very quickly?

I am looking forward to hearing from you soon.

Thank you very much.
